Paper Mario

Paper Mario is a role-playing game developed by Intelligent Systems for the Nintendo 64. It was later re-released for the iQue Player in 2004, the Wii's Virtual Console in 2007, the Wii U's Virtual Console in 2015, and Nintendo 64 - Nintendo Switch Online in 2021.

Paper Mario has the player taking control of Mario on his quest to rescue Princess Peach and save the Mushroom Kingdom from Bowser, who has stolen the mythical Star Rod of Star Haven and used its wish-granting powers to make himself invincible. To stop Bowser and rescue Princess Peach, Mario and company must save the seven Star Spirits; magical beings who have been sealed in cards by Bowser with the power to nullify the Star Rod, as well as the original owners of the Star Rod.

Paper Mario's gameplay is a blend of traditional Japanese role-playing games and Mario-esque platforming features; Mario has the ability to jump in both the overworld and in battle, and jumping remains one of the most important actions in the game. The player controls Mario and a party of followers as they journey through the Mushroom Kingdom, exploring dungeons, managing stats, and battling enemies. The title refers to the game's arts and crafts aesthetic; nearly every character in the game is drawn as a flat 2D sprite, revealing itself as paper-thin when turning around, and many elements of the environments are also depicted as 2D sprites.

Paper Mario was initially in development for the Nintendo 64DD under the name Super Mario RPG 2 (also called Mario RPG 2 or Mario RPG 64 ) and intended as a sequel to Super Mario RPG: Legend of the Seven Stars. Concept art posted by Super Mario RPG artist Kazuyuki Kurashima on his Instagram account in 2019 indicated that Samus Aran and Link from the Metroid and The Legend of Zelda franchises would have appeared alongside Mario characters. It later became the first installment of the Paper Mario series and would go on to receive several sequels; the first in the same style of gameplay (Paper Mario: The Thousand-Year Door), followed by several in different playstyles (Super Paper Mario, Paper Mario: Sticker Star, Paper Mario: Color Splash, and Paper Mario: The Origami King).

Opening
The story opens with a place that lies far beyond the sky and far above the clouds, called Star Haven. Within the sanctuary of Star Haven lies the Star Rod, which can grant any and all wishes. The seven Star Spirits use this artifact to watch over and protect the Mushroom Kingdom. Until one day, Bowser and Kammy Koopa appear in the sanctuary. Bowser shatters the protective seal over the Star Rod and grabs it in hopes of using its power to defeat Mario. The Star Spirits are then trapped inside cards by Kammy Koopa.

Mario and Luigi receive an invitation to a party from Princess Peach. Upon arriving at the castle full of guests from all over the Mushroom Kingdom, Mario proceeds to meet the Princess. However, their meeting is interrupted by Bowser's Castle rising from the earth beneath Peach's Castle and lifting both buildings into space. Bowser and Kammy Koopa then appear to kidnap the princess. Mario attempts to fight off Bowser, but finds himself outmatched when Bowser takes out the Star Rod and uses it to make himself invincible. Mario is then cast out of a window and plummets back towards the ground, which allows Bowser to kidnap the Princess.

Prologue: A Plea from the Stars
The prologue begins with the seven Star Spirits manifesting over Mario on the ground, and use their remaining power to save his life. Mario's unconscious body is then found by a family of friendly Goombas, who carry him back to their village. While knocked out, he receives a vision from one of the Star Spirits, Eldstar, urging him to go to Shooting Star Summit. After waking up, Mario meets the Goomba family who found him, including Goombario, the family's son. Kammy Koopa appears to confirm that Mario is still alive, and blocks the gate out of Goomba Village with a yellow block. After a short venture that involves Mario saving the family's grandfather and a battle with a local troublemaker called Jr. Troopa, Mario breaks the block using Goompa's hammer. Goompa requests that Goombario join Mario on his quest and together they leave Goomba Village. While traveling Goomba Road, the connecting strip of land between Goomba Village and Toad Town, Mario and Goombario are confronted by the Goomba King and his two lackeys, the Red & Blue Goomba Bros. The protagonists manage to defeat them and reach Toad Town, where they continue on towards Shooting Star Summit.

Atop the summit, Mario is greeted by manifestations of the Star Spirits, who tell Mario the story of how Bowser stole the Star Rod. They further explain that the cards in which they have been trapped are now divided among Bowser's forces, and that Mario must save and release them. In doing that, Mario will gain a power called the Star Beam, which can be used to break Bowser's invincibility and allows Mario to defeat him.

Meanwhile, in the sky, Princess Peach finds herself trapped in her room. Not knowing what to do, she wishes for someone to help her, which summons Twink, a Star Kid who only recently ascended to Star Haven. Though unable to help Peach deal with Bowser directly, he agrees to deliver the Lucky Star, Peach's magical pendant, to Mario and help in whichever way he can.

As Mario returns from Shooting Star Summit, Twink runs into him and delivers the Lucky Star which enables Mario to use Action Commands. Upon re-entering Toad Town, Mario learns that Merlon, the local fortune-teller, is looking for him. Merlon informs Mario that his search for the Star Spirits will lead him to the fortress east of Toad Town, where the Koopa Bros. are holding a Star Spirit captive.

Chapter 1: Storming Koopa Bros. Fortress
After leaving town, Mario finds the way to the Koopa Bros. Fortress inaccessible to him, so he takes another path to Koopa Village. He arrives to see the local Koopa Troopas being harassed by Fuzzies, who are stealing their shells. One of the victims is Kooper, who asks Mario for assistance in getting his shell back. Upon returning it, Kooper is so grateful that he joins Mario's group.

With the help of Kooper's special ability, Mario is able to reach the Koopa Bros. Fortress. During his assault on the fortress, he triggers a trapdoor which drops him into a prison cell full of Bob-ombs. One of them, Bombette, explains that they were working for the Koopa Bros. but then later got locked up for revolting against them. She helps Mario and his friends escape by blowing up a crack in the cell wall and decides to accompany him. The group travels to the top of the fortress where they confront the Koopa Bros.. They initially try to scare Mario off with a fake Bowser suit, but their attempt fails, so they decide to fight Mario in a direct battle. They are eventually defeated and knocked off the arena into the prison cell from earlier. With the Koopa Bros. defeated, Eldstar is released and adds his powers to Mario, teaching him the ability to use Focus, as well as the special move Refresh.

Trapped in her castle in the sky, Peach remembers the existence of a secret passage that leads out of her room. She and Twink use it to leave the room and move to another room in the castle, where they find Bowser's diary. By reading it, Peach and Twink learn that another Star Spirit is being held captive in Dry Dry Desert. At that moment, Bowser enters the room and catches the Princess reading his diary. Enraged, he summons two guardsmen to escort her back to her room, while Twink quietly leaves the scene undetected to inform Mario of the next Star Spirit's location.

After returning to Toad Town, Mario and his friends head towards the train station in the south district of Toad Town, where Dry Dry Railroad leads to Mt. Rugged.

Chapter 2: The Mystery of Dry, Dry Ruins
At Mt. Rugged, a mountain beyond which the desert lies, Mario runs into Parakarry, a distressed mailman who has dropped letters all over the area and asks Mario for assistance. Mario accepts to find the letters, and Parakarry joins Mario's group out of gratitude.

After crossing Dry Dry Desert, Mario enters a settlement called Dry Dry Outpost. After exchanging some items for information, he meets with the town leader Moustafa, who hands him a Pulse Stone and tells him to let it guide him to the resting place of Dry Dry Ruins. Following the Pulse Stone's signal through the desert, Mario finds a stone pedestal to set the stone into. The entrance to Dry Dry Ruins rises out of the sand before Mario, and he enters the ruins.

Inside, a ghostly wail tries to warn Mario against continuing his descent. Mario keeps going until he finds Tutankoopa, the source of the voice and the guardian of the second Star Spirit. After battling Mario and losing, he is chased out by his Chomp, allowing Mario to free the Star Spirit Mamar.

In Peach's Castle, Bowser visits the Princess in her room. He tells her that, with Tutankoopa defeated, he now intends to stop Mario by using Tubba Blubba, who is allegedly invincible. However, Kammy Koopa rushes in to tell Bowser that the Star Spirit guarded by Tubba Blubba has escaped. Once they leave, Peach and Twink hypothesize that even an invincible person must have a weakness. After some investigating, their theory is confirmed by an overheard conversation between Bowser's men, though Peach never learns what the weakness is exactly.

After returning to Toad Town, Mario finds a cowardly Toad guard who claims he saw a ghost vanish into Forever Forest. Mario investigates and meets Bootler, a servant of Lady Bow who requests Mario's presence in her mansion in the heart of the forest.

Chapter 3: The "Invincible" Tubba Blubba
Mario follows the invitation through the maze-like forest and finds the mansion he was referred to. After overcoming the challenges inside, Mario meets Lady Bow. He is told about Tubba Blubba, the threat he poses, and the secret that may be related to his weakness. Bow then uses the Star Spirit Skolar the Boos found and captured as leverage to get Mario to defeat Tubba Blubba. She also joins Mario because she is tired of seeing her fellow Boos suffering, and because Mario will need her to get to Tubba Blubba's Castle.

The group leaves Forever Forest and heads towards Gusty Gulch. There, they witness Tubba Blubba attacking a ghost village and devouring a Boo. Mario and his friends follow Tubba Blubba to his castle and sneak their way up to the master bedroom. In a chest next to the bed, Mario finds Yakkey, a talkative key who tells them that he is the literal key to Tubba Blubba's secret inside Windy Mill. Yakkey concludes that Mario must be a thief, so he alerts Tubba Blubba of them. With a furious Tubba Blubba chasing them, Mario and his friends escape the castle, run all the way down to Windy Mill, and unlock it with the key.

Inside Windy Mill they find Tubba Blubba's secret, which turns out to be his heart that has been controlling the body remotely. After Mario beats it, the heart escapes outside the mill, where Tubba Blubba's body has caught up with Mario. Heart and body re-unite and attempt to fight Mario again, but with the heart being back inside Tubba Blubba's body, he is vulnerable again. After his defeat, Tubba Blubba decides to release all the Boos he has eaten, and reveals he is really a sensitive guy who did not like being scared by the Boos. Lady Bow, pleased with the outcome, holds up her part of the bargain and frees Skolar.

In Peach's Castle, Twink and the Princess decide to sneak out of the bedroom again. They immediately run into Bowser and Kammy Koopa, who are discussing how Mario's next target will be Shy Guy's Toy Box, and pondering what the best way to defeat him there would be. Bowser then tries to coax Peach into telling him about Mario's secret weaknesses, and sends Kammy Koopa to impede his progress using this information.

After returning to Toad Town from his trip to Forever Forest, Mario finds the town overrun with Shy Guys stealing people's belongings. Mario and his friends are able to trace the source of the Shy Guy attacks to one of the vacant houses in the residential area. By hiding inside with Lady Bow's ability, Mario is able to observe one of the Shy Guys open a hidden door to a secret back room hiding the Shy Guy's Toy Box.

Chapter 4: Trials in the Toy Box
Inside the toy box, Mario runs into obstacles he cannot overcome by himself, such as the railway system missing a train, or Gourmet Guy blocking the way. In these cases the Mario must fight Shy Guys, retrieve items that were stolen from Toad Town citizens, and return them to their owners. At certain points, Kammy Koopa appears and attempts to execute Bowser's plan by summoning obstacles related to the answers Peach gave as Mario's weaknesses.

Eventually, Mario reaches Red Station, where he encounters and battles the Big Lantern Ghost, who upon defeat drops his lantern and flees. Inside the lantern is Watt, a Li'l Sparky who was captured by the Shy Guys and used as a light source. Being grateful for being rescued, Watt joins Mario's group.

After that, Mario locates the Shy Guys' central base of operations, where he meets their leader, General Guy. He rallies his men and sends several waves of Shy Guy infantry against Mario and his friends, who dispatch them one after another, and eventually himself. After defeat, General Guy and his Shy Guys flee, leaving Mario able to rescue Muskular, the fourth Star Spirit.

In Peach's Castle, the Princess encounters Gourmet Guy during one of her secret trips outside of her room. Gourmet Guy tells Peach that he is technically obligated to let the guards know he saw her wandering around, but that he might look the other way if she went into the castle kitchen and baked him a cake. Peach complies and, with Twink's help, bakes a strawberry cake, which makes Gourmet Guy ecstatic. Once he regains his composure, he informs Peach that the next Star Spirit is being held on Lavalava Island, an island to the south. The Princess ends up being spotted by Kammy Koopa and escorted back to her room.

Mario heads to the Toad Town harbor where he meets Kolorado the archeologist and a whale. The whale offers to carry Mario and his friends over the ocean, but only if Mario enters his belly to cure a bellyache he has been having. Inside, Mario finds a Fuzzipede irritating the whale's belly. After fighting the Fuzzipede and getting it out of the whale's belly, Mario's group ride the whale to Lavalava Island, with Kolorado joining them to find treasure.

Chapter 5: Hot, Hot Times on Lavalava Island
On the island, Mario and Kolorado find the entrance to Mt. Lavalava inaccessible due to a lava river. They head to the nearby Yoshi's Village to ask the locals for information, but the village is in a state of panic because their kids went missing in Jade Jungle. Mario heads into the Jungle to search the missing children and finds their caretaker, Sushie, stuck in a tree. After being freed, she joins Mario to locate all of the missing Yoshis and bring them back to their parents. With the kids returned and the villagers pacified, Mario is able to talk to the Village Leader about reaching Mt. Lavalava. The Yoshi suggests seeking out Raphael the Raven in Jade Jungle. Mario finds Raphael on top of a large tree in an area accessible only with the Jade Raven. Raphael offers his assistance by summoning his Raven followers to construct a set of ropeways to help Mario across the lava river.

Inside, Mario and Kolorado explore the caverns of Mt. Lavalava, with the former doing most of the work and the latter suffering various injuries while trying to be useful. Deep inside the volcano, they meet Lava Piranha, the guardian of the Star Spirit. Mario defeats it and releases Misstar, but at that moment the volcano starts to erupt. As they flee, Kolorado notices a treasure chest which he presumes contains the treasure he has been looking for. Before the lava reaches them, Misstar grabs him and Mario's group and escapes the volcano through the caldera. The treasure chest gets blown out of Mt. Lavalava and into Jade Jungle.

In the meantime, Peach encounters Bowser's minions setting up a quiz show. Since they are one player short, they ask Peach to participate. During the show, several of the questions reveal that there is a Star Spirit held captive in a place called Flower Fields. For her participation in the game she is handed a Sneaky Parasol, an item that can copy the appearance of whoever the holder is facing. Before she can make any use of it, Bowser enters the room, spots the Princess, and has her escorted back to her room.

In Toad Town, Twink informs Mario that the sixth Star Spirit is hidden in Flower Fields. To get there, Mario must find the four Magical Seeds from the Bub-ulbs across the world. Kolorado has found one, which he trades for Mt. Lavalava's treasure in the chest, the Volcano Vase. Planting the Magical Seeds in Toad Town creates the doorway to Flower Fields.

Chapter 6: Dark Days in Flower Fields
When Mario enters the Flower Fields, he sees the place shrouded in clouds. The Wise Wisterwood tells Mario that the clouds are the result of Huff N. Puff, who is using his Puff Puff Machine to cover Flower Fields in clouds. Because of this, the Sun cannot rise to the sky. Mario thus needs to destroy the Puff Puff Machine to make the Sun rise to the sky, and help the local flowers to acquire a Magical Bean, Miracle Water and Fertile Soil. These will create a beanstalk up to the Cloudy Climb where Huff N. Puff is hiding with the Star Spirit. Mario also meets a strange Lakitu called Lakilester who insists his name is Spike. He fights Mario under the orders of Huff N. Puff, but after losing decides to join Mario because he sees no reason in working for Huff N. Puff. He then fights a group of Lakitus and destroys the Puff Puff Machine, before planting the Magical Bean. When the beanstalk is grown, Mario heads to the Cloudy Climb and defeats Huff N. Puff for the sixth Star Spirit, Klevar.

Back at the castle, Peach uses the Sneaky Parasol to turn herself into one of the guards, allowing her to move around the castle without fear of getting caught. Peach then learns that Kammy Koopa has finished preparations for something to defeat Mario. Before she can find out what it is, however, Kammy notices a peculiar smell coming from her disguise and turns her back to normal with a spell. She is then taken back to her room yet again.

Back in Toad Town, Mario finds a Ninji waiting for him at Merlon's house. The Ninji informs that Merle of Starborn Valley has something important to tell Mario, and that he must go there. Mario finds an Warp Pipe to Shiver City in Toad Town Tunnels.

Chapter 7: A Star Spirit on Ice
In Shiver City, Mario finds out that he cannot go to Starborn Valley unless the mayor grants him permission. However, he finds the mayor unconscious on the floor and becomes a suspect for the mayor's murder. With novelist Herringway's help, the truth is revealed: the Mayor was knocked out by the falling box containing a gift for the novelist. With the mystery solved, the mayor allows Mario to go to Starborn Valley.

On the way to Starborn Valley, Mario faces Jr. Troopa again, as well as a mini-boss called Monstar.

Once Mario reaches the Starborn Valley, he meets Merle, who tells Mario to go to the Crystal Palace, where the seventh Star Spirit is being held. He then gives Mario a scarf, telling him to use it on something special, then telling Mario to go and ask Mayor Penguin for the other special item, a bucket. Mario goes to a line of snowmen on the path between Shiver City and Starborn Valley, one missing a scarf and the other missing a hat. Mario gives the items to the respective owners. The snowmen thank him and open the way to the Crystal Palace. Along the way to the palace, they meet the spirit of Madam Merlar, who gives Mario the Star Stone, to reach the palace. Once they reach the Crystal King at the palace's back, Mario defeats him for the final Star Spirit, Kalmar.

In Peach's Castle, Kammy Koopa informs Bowser that Mario now has all seven Star Spirits. Bowser orders the Koopa Troop to their battle stations and has the princess tied up to keep her out of mischief. Twink tries attacking him, but Bowser simply swats him out of the window.

Meanwhile, Mario and the team reach Star Haven with the help of the seven Star Spirits, acquire the Star Beam, and use the power of the Star Spirits to travel to Bowser's Castle.

Chapter 8: A Star-Powered Showdown!
After going through Bowser's Castle, falling for traps, solving puzzles and getting attacked by Jr. Troopa one last time in the process, Mario and his team find Princess Peach and Bowser in the same place where Mario first encountered Bowser at the start of the game. The Star Beam lets Mario negate Bowser's invincibility and beat him, but Bowser takes his loss as a warm-up and flees with Peach to the castle roof, followed by Mario. Kammy Koopa activates her creation, the Power Platform, to pump Bowser up in both power and size; when he powers up with the Star Rod, Mario finds that the Star Beam is now ineffective.

Meanwhile, Twink frees the Princess, and the two battle Kammy. As Peach uses Focus, Twink slowly becomes stronger to the point where he becomes immune to Kammy's attacks. Kammy remembers before her defeat that the Stars get their power from the wishes of ordinary people. Twink urges the Princess to make a wish for everyone in the Mushroom Kingdom while he goes to help Mario and the Star Spirits. Peach's wish fills the Star Spirits with more power; thus enabled, as Mario recovers, the Spirits upgrade the Star Beam to Peach Beam, which cuts through Bowser's enhanced power. After a lengthy battle with Bowser that ultimately leaves the Koopa King defeated, Mario returns the Star Rod to the Star Spirits. The Power Platform and Bowser's Castle begin to self-destruct, but the Star Spirits protect Peach's Castle from the explosion and restore it to its spot.

Several days later, Mario, his partners, and many others receive invitations from Princess Peach for another party. After a speech by Peach where she thanks everyone for their collective effort in restoring the peace to the Mushroom Kingdom, the staff credits begin to roll as the scene switches to a parade with nearly the entire cast participating. At the end, Mario and Peach walk to Mario's House and watch a fireworks display, which continues on until the player turns off the game.

Gameplay
For the majority of the game, the player controls Mario as he travels through various locations in the Mushroom Kingdom. The game is divided into chapters, with each chapter generally being set in a different area. Many of these areas contain NPCs and/or enemies. Some NPCs, such as Tayce T., can provide Mario and his party with services.

On his way, Mario and his friends use various abilities that help them progress on their adventure. Mario can jump to reach higher ground, traverse gaps, or reach blocks floating above his head. Early on, Mario obtains a hammer that is used to break larger blocks and other obstacles. Throughout the game, the player will obtain special items that upgrade Mario's jump and hammer and give him new abilities.

At the end of each chapter, an interlude occurs in which the player takes control of Princess Peach. Peach does not have access to Mario's abilities, party members, or inventory. Items picked up as Peach can be deposited in the Mysterious Treasure Chest in the castle storage room so they can later be picked up by Mario from the chest's counterpart at Merluvlee's Place.

Objects
A list of reoccurring devices that Mario can encounter during his quest. Some of them are beneficial and help the player by making traveling easier, containing items, or making Mario and his friends stronger. Others serve as obstacles and require a specific ability, item, or party member to overcome.

Party members
An important part of Paper Mario is the party member system. Throughout his journey, Mario befriends various residents of the Mushroom Kingdom who join him on his quest, known as party members. Every party member has an overworld ability that can be used by pressing and usually serves to aid in traversing the landscape in some way, such as Parakarry's flight or Watt's ability to light up dark areas and reveal hidden blocks. Additionally, party members can aid Mario in battle by using various moves, many of which are based on their overworld abilities.

Ranking-up party members
Each party member joins Mario at their most basic rank and is able to choose from two moves in battle. If the player manages to locate a Super Block, they may upgrade one of their currently available party members to the next rank, which increases the damage output of all their attacks and lets them learn a new move.

The first time a party member is upgraded, they advance to Super Rank. To upgrade them even further, Mario needs to be in possession of the Ultra Stone, which allows party members to reach Ultra Rank. At Ultra Rank, each party member has four moves and cannot be upgraded further. There are 16 Super Blocks in the game in total, enough to advance every party member to their final rank.

Battle system
Paper Mario uses a turn-based side-view battle system. Enemies are visible on the overworld and initiate a battle if the player makes contact with them. The manner in which this happens also determines whether the battle starts in Mario's or the enemies' favor; successfully attacking an enemy on the overworld nets Mario a preemptive hit on an enemy, referred to as a first strike, whereas getting hit by an enemy attack gives the enemy a free turn to damage Mario before the fight starts proper.

On the battle screen itself, Mario and one party member of his choice find themselves on the left side of the screen, with the enemy group occupying the right side. What kind of enemies Mario faces is determined by which type of enemy initiated the battle on the overworld, with several different formations being possible.

To win a battle, the player must eliminate all enemies on the opposite side, either by defeating them or by making them run away. An enemy counts as defeated if their Heart Points (HP) are dropped to zero. Likewise, if Mario's HP drop to zero without a Life Shroom in his inventory, the battle is lost. The player can keep track of Mario's HP and various other stats with the battle statistic on the top side of the screen.

During battle, the player and the enemies take turns attacking. The damage an attack will do is determined by the attack's power minus the target's defense rating. During the player's turn, Mario and the currently active party member each get an action, the order being changeable by pressing.

Mario's action
Mario's main attack options all fall into the two categories of "hammer" and "jump". The condition of the targeted enemy may make one or both of these options either inaccessible or inadvisable. Hammer attacks have a limited range and can only attack the first ground-bound enemy of a group. Jump attacks on the other hand can reach past enemies standing in the way, or attack enemies flying out of reach, but jumping on a spiked or otherwise hazardous foe cancels the attack and makes Mario take 1 HP of damage.

Both hammer and jump attacks can be customized by outfitting Mario with certain Badges. Custom hammer or jump attacks usually consume Flower Points (FP) and cannot be used if the required amount is not available.

Once unlocked by finding the correlating Star Spirits, Mario is also able to use special moves. These can have a wide variety of effects depending on the move used, but all of them consume a certain amount of Star Power (SP). Mario's SP is represented by a series of colored bars at the top of the screen, and each bar equals one unit. A small amount of SP is regained with each turn, but more may be restored by using the Focus command.

Aside from hammer and jump attacks or special moves, Mario can also use items from his inventory, do nothing, or attempt to run away. During an escape attempt, a bar appears that may be anywhere between empty and completely full, depending on the number and level of enemies. The player can slowly fill the bar by repeatedly tapping. While escaping is in progress, an indicator slides back and forth between the right and left side of the bar until it stops. If it stops on the filled portion of the bar, the escape attempt is successful and Mario returns to the overworld (while losing a few coins in the process). Otherwise Mario wastes his action and the battle continues.

Party member action
The party member's options are more limited than Mario's, but can be increased by equipping Badges. Under normal circumstances, a party member can either attack or do nothing, the latter of which skips their action. Depending on their level, a party member can have up to four attacks in their repertoire. At least one of these attacks is always free to use, whereas other, more potent attacks cost Flower Points.

The party members do not have their own FP and instead draw from the same pool as Mario does. Special care has to be taken with party members who use jump-type attacks, because they are susceptible to the same hazards as Mario's jump command, which means the party member can get injured by jumping on certain enemies.

Only one party member can be used during battle, but the currently active one can be swapped out for a different party member during battle. This uses a turn unless the Quick Change Badge is equipped.

Enemy action
After both Mario and his party member have taken their actions, all able enemies will then attack one after another. In most cases, enemies will target Mario, but some attacks can hit the party member, either separately or additionally to Mario. Since Mario's party members do not have HP themselves, every time they get hit, they will acquire the injured status effect, which prevents them from taking action for a few turns.

Once all enemies have attacked, the current turn ends and the next one starts from the beginning again, with the player choosing Mario and his party member's actions.

Status effects
Some items and attacks afflict their targets with conditions that affect their battle performance. In most cases, these status effects are temporary and the number of turns they will last is denoted along with an icon that indicates what the status effect is. Status effects only apply in battle and wear off once the player returns to the overworld.

Regular effects Unique effects

Action Commands
After Mario receives the Lucky Star at the foot of Shooting Star Summit, the player is able to use action commands in battle. From then on, whenever Mario or his party member execute an attack, a prompt shows up and input from the player is required. If the action command is successful, attacks will do bonus damage or have other additional effects.

Likewise, if during an enemy's turn the player presses right before an attack connects, Mario will guard against it and the damage will be reduced by 1. Additionally, if an enemy attack would cause a status effect, successfully guarding against it cancels the effect.

End of battle
Once all enemies have been eliminated, Mario receives experience in form of Star Points. The amount of Star Points received depends on the levels of the defeated enemies as well as that of Mario himself, and may be anywhere between none and 100. Whenever Mario's Star Point count reaches 100, his level increases by one and the player gets to choose whether to increase Heart Points, Flower Points, or Badge Points.

After the battle ends, the game shifts back to the overworld. The enemy that triggered the battle disappears and leaves behind coins, hearts or flowers that restore HP and FP respectively, or items.

Items
Items in Paper Mario come in two categories: Regular items and key items.

Regular items are helpful goodies with a variety of effects, like restoring HP or FP, or dealing damage to enemies. This type of item is commonly sold in shops. They also occasionally get dropped by defeated enemies, can be found in ? Blocks, or acquired by having Tayce T. cook.

Mario can carry up to ten of these items, and they can be used by pressing. If an eleventh item is picked up, one of the other 10 has to be discarded before it can be added to the inventory. Up to 32 regular items can be stored by using the check system in shops.

Key items are unique objects that are used to progress through the story, or for the completion of sidequests. They are listed separately from regular items and do not affect Mario's carrying capacity. If a situation requires a key item and Mario has said item in his possession, a prompt shows up and the item can be given away. Key items stay with Mario until they are needed; They cannot be dropped, sold, or stored.

Badges
Badges are helpful items that grant Mario and his friends a number of active or passive bonuses when he equips them. The effects can range from changing the way Mario's overworld abilities work, to affecting his stats or giving him new attacks, to increasing the versatility of his party members.

Mario has a stat called Badge Points (BP), which affects how many Badges can be equipped at the same time. Every Badge has also a BP rating, which tells the player how many free BP are needed to equip the Badge in question. Equipping a Badge will disable an amount of Mario's BP equal to the Badge's BP rating, and unequipping it will free those BP up again. Mario starts the game with three BP and gains an additional three every time the player chooses to upgrade BP during a level up.

Badges can be found in red ? Blocks, in some treasure chests, or lying around in dungeons. They can also be purchased from Rowf's Badge Shop in central Toad Town, gotten as rewards from side quests, and traded in exchange for Star Pieces by Merlow at Merluvlee's Place.

Star Spirits and Special Moves
The seven Star Spirits live in Star Haven as the guardians of the Star Rod. The story of Paper Mario begins with their fall from power, when Bowser and Kammy Koopa attack Star Haven, steal the Star Rod, and capture the Star Spirits. Rescuing them is one of the main objectives of the game, as they are the only ones who can counter the Star Rod's power and help Mario triumph over Bowser.

The captured Star Spirits are kept separately and spread all over the Mushroom Kingdom. Mario rescues one Star Spirit at the end of every chapter, bar the final one, after defeating the chapter boss. With every Star Spirit returning to Star Haven, Mario's Star Power increases by one and he learns a new Special Move.

Once every Star Spirit has been rescued, Mario gains access to Star Haven, where he obtains the ultimate star power: the Star Beam. The spirits also permit him to use the Star Ship, a vessel able to reach Bowser's Castle in the sky.

Regular powers
Special Moves gained at the end of every chapter, except chapter 8.

Special case powers
Special Moves that cost no SP to use and serve a unique purpose.

Friendly NPCs
The overworld of Paper Mario is filled with many characters that Mario can talk to. When approached, a speech bubble icon will appear above their head which signifies they can be spoken to.

Star Pieces


Star Pieces are golden octahedral star fragments that can be found all over the Mushroom Kingdom. There are 160 in total. They can be collected and brought to Merlow at Shooting Star Summit in exchange for Badges.

A lot of Star Pieces can be found lying around in the overworld, usually hidden behind objects. Some Star Pieces are buried beneath hidden floor panels that require either the Spin Jump or the Ultra Hammer to collect. Star Pieces are also often given away as rewards or sold as wares by NPCs.

Chuck Quizmo's quizzes


Chuck Quizmo is a character who can randomly be encountered in one of the game's many towns. Upon finding him, the player has the opportunity to partake in a quiz show. Chuck Quizmo will ask the player a trivia question about the game and present them with three possible answers. If the correct choice is selected, the player receives a Star Piece. Otherwise Chuck Quizmo has to be found again for another try. There are 64 questions in total the player can answer.

Toad Town Dojo
After Mario talks to the Star Spirits on Shooting Star Summit and obtains the Lucky Star, the Toad Town Dojo opens. The dojo is located on the second story of the Shroom Grocery building. Here Mario can fight against Chan and Lee, as well as the dojo's Master himself.

Fighting in the dojo does not give Mario Star Points, but with each win the player receives a degree and unlocks the next fight. Defeating the Master's third form earns Mario the Diploma for besting the strongest enemy in Paper Mario.

Koopa Koot's favors


Once the player reaches Koopa Village in chapter 1, they have the opportunity to meet Koopa Koot, an elderly Koopa Troopa infamous among his acquaintances for asking favors of people.

When speaking to Koopa Koot after resolving Koopa Village's Fuzzy problem, he will ask Mario for a favor, which usually entails obtaining a specific item and bringing it to him. Upon completion of the favor, Koopa Koot will usually reward Mario with a single coin. In some cases however, the reward will be three Star Pieces in a bulk, or an item that unlocks new minigames in the Toad Town Playroom.

Tayce T.'s recipes


Tayce T. is an elderly Toad woman who lives in Toad Town. She is initially inaccessible due to debris blocking the road to her house, but can be talked to after the Koopa Bros. have been defeated.

Mario can give Tayce T. ingredients which she will turn into new items by cooking them. At first only one item can be given to her at a time, but after bringing her the Cookbook from Shy Guy's Toy Box in Chapter 4, the player unlocks the ability to have her use two ingredients. The blackboard in Mario's House is keeping track of how many recipes have been found and can be checked at any time.

Letter delivery
In various locations of the Mushroom Kingdom, Mario can find letters that have been dropped by Parakarry. Once Parakarry has joined Mario's group, Mario can deliver these lost letters to their intended recipients by talking to them while Parakarry is the active party member. Doing so rewards the player with Star Pieces, another letter, or other items.

Services
A lot of different vendors, establishments, and merchants can be found all over the Mushroom Kingdom. Most of them offer their services for coins which can be found inside ?-Blocks or earned from battling enemies.

Toad Houses
Toad Houses are establishments that can be found in all major towns featured in Paper Mario. They can be recognized by their signs which show a picture of a Toad's head. Toad Houses serve as hotels and Mario and his friends can rest in them to restore Heart Points, Flower Points, and Star Power. Unlike inns in traditional RPGs, they do not charge money for this service.

Almost all Toad Houses are managed by Toads, the sole exception being the one in Star Haven which is owned by a Star instead.

Item Shops


Scattered across the Mushroom Kingdom are various common goods stores, identifiable by their Fire Flower sign. Here the player can take their coins to buy items that cause different effects in and out of battles. Additionally, they may get a coin refund by selling items they do not want.

Most items can be sold to the shopkeepers for a set price at every shop, however, some items will sell at a higher price depending on the location of the shop and the item itself. Mario can make a profit by purchasing an item at a low price from one store and selling it to another that will buy it at a higher price.

Item Shops also offer a check system that allows the player to store and withdraw items. This storage space is shared by all stores, which means the player can store an item in one shop and then later withdraw it from another. Up to 32 items can be stored that way.

Merlon's house
Merlon is Toad Town's local fortune-teller. His services become available after Mario has visited Shooting Star Summit and gotten the Lucky Star. For a fee of five coins, Merlon will foresee Mario's future and give the player a hint about the next game objective.

Merluvlee's Place
Merluvlee is another fortune-teller who lives at the foot of Shooting Star Summit. She will divine the locations of Star Pieces, Badges, and Super Blocks. She charges 5 coins, 20 coins, and 30 coins for each of them respectively.

Her house also contains the counterpart to the Mysterious Treasure Chest in Peach's Castle. Any items that Princess Peach puts into the chest on her end can be retrieved by Mario here.

Merluvlee's brother Merlow can be found on the second floor of the house. He informs Mario that he collects Star Pieces and is willing to trade Badges for them. Getting Badges from Merlow is the main purpose of collecting Star Pieces.

Toad Town Post Office
The Toad Town Post Office is a building located in central Toad Town, across the street from Merlon's house. Over the course of the game, letters addressed at Mario's party members arrive there, written by different characters Mario met on his journey. The player can visit the post office at any time and talk to the postal worker in charge to view the letters. There is no benefit to reading the letters, but the service is free and reveals what became of the sender after their encounter with Mario.

Mario himself also receives letters during the game. These letters are not stored at the post office and can be found in the bedroom of Mario's House.

Badge Shop
The Badge Shop is an open-air store located in the central part of Toad Town, across the street from the gate to Flower Fields. It opens for business after the Koopa Bros. have been defeated in Chapter 1. The player can purchase Badges in exchange for coins.

Sixteen different Badges can be purchased from the Badge Shop, although only three will be available at a time. The selection changes randomly over time until all Badges have been bought.

Oink-Oink Farm


Once the Koopa Bros. have been defeated and the road to the southern part of Toad Town has been cleared of debris, Mario can visit Oink-Oink Farm. For 10 coins, the player can purchase an egg that will hatch into a Li'l Oink and move into the nearby pigpen.

The pen can hold a maximum of 10 animals. If an additional egg is bought while the pen is full, the oldest Li'l Oink will escape and leave behind an item correlating to its color. The player can use this to obtain various items, including ones that are hard to obtain otherwise.

Merlee's tent
Merlee is a wizard who set up her shop in the back alley of Dry Dry Outpost. For a fee of either 5, 20, or 50 coins she can cast a magic spell on Mario that has a variety of positive effects. The amount of coins paid determines how long the spell is going to last; The more coins were paid, the longer the spell remains.

From the moment it is cast until it runs out, the spell will randomly take effect before or after certain actions, mostly during battles. Once the spell has ran out, the player has to return to Merlee and pay her again if they wish to keep the beneficial effects.
 * If it takes effect before Mario attacks, the damage of his attack will increase by three.
 * If it takes effect during the enemies' turn, Mario's defense will increase by three.
 * If it takes effect once all enemies have been defeated, it doubles the amount of Star Points received.
 * If it takes effect right after a battle, it will increase the amount of coins dropped by the enemy.

Chet Rippo
Chet Rippo is a pudgy bird-like creature located in the residential area of Toad Town. When talked to, he informs Mario that he is able to increase one of his stats for 39 coins. If the player decides to use Chet Rippo's services, the stat they selected will increase by two stages, while the two stats that weren't selected each drop by one stage. This service can be used to re-adjust Mario's stats in case the player does not feel content with their past level up choices.

Rip Cheato
Rip Cheato is a merchant living underneath the blue house next to Tayce T.'s. Initially the front door to his domicile is locked and thus it has to be accessed through Toad Town Tunnels by having Bombette destroy a wall. After Rip Cheato has been found, his house can be unlocked from the inside for easier access.

The merchant's services are similar to that of a regular item shop, offering wares in exchange for coins. However, Rip Cheato only sells one item at a time, all of his goods cost 64 coins, and the player does not know in advance what is being offered. Rip Cheato's offers follow a certain order and once his stock is exhausted after ten purchases, he only sells Dried Shrooms from then on.

Virtual Console differences
The Wii Virtual Console version has more framerate drops than the Nintendo 64 version, but also loads more quickly when moving between areas. Special effect attributes have been altered to reduce the risk of seizure or are different due to emulation issues: the brightness of light effects from Super Blocks have been reduced, the screen dims when an explosion occurs, fire/explosion effects are now solid colors, and magic/transformation wave effects no longer have flashing colors of white and yellow and are waves of purple and pink.

The Wii U Virtual Console version is darker throughout the whole game, but has a smoother framerate not unlike the Nintendo 64 version. Fire/explosion effects match that of the original version (albeit darker), but the magic/transformation wave effects are altered, but in a different way than in the Wii version. In addition, the light effects are malformed and have a black glow. Loading is as fast as the Wii version.

Similarities with Super Mario RPG: Legend of the Seven Stars
Paper Mario shares many elements with its spiritual predecessor Super Mario RPG: Legend of the Seven Stars, seeing as it was initially intended to be a sequel. These similarities include:
 *  Paper Mario was originally going to be called Super Mario RPG 2, but was later renamed "Super Mario Adventure" (while still in development) due to legal reasons. Eventually, it received its finalized international title to emphasize the unique graphical style of the game.
 * As with Super Mario RPG, Bowser is the very first boss to be fought in the game.
 * After the cutscene that takes place when Mario is defeated by Bowser, the Paper Mario logo is displayed similarly to how the Super Mario RPG logo (sans subtitle) is displayed after Exor crashes into Bowser's Keep and destroys the Star Road.
 * Redesigned versions of Star Hill and the Chancellor from Super Mario RPG reappear, although this is lost in translation in the international versions, with the former being renamed Shooting Star Summit and the latter the Toad Minister.
 * The Shy Guy riot in Toad Town is similar to Mack and the Shysters' takeover of the Mushroom Kingdom in Super Mario RPG.
 * Both Paper Mario and Super Mario RPG contain karate dojos.
 * The Master is Paper Mario's equivalent of Jinx, as they are both powerful senseis that are fought three times (with each battle getting harder), and are completely optional. The Master also shares the role of an optional boss harder than the final, main boss, like Culex.
 * Both games have plots that involve finding seven stars and have something to do with wishes not being granted due to what the games' main antagonists have done.
 * The opening storylines of both games begin with the usual "Mario battling Bowser to save Peach" scenario when Mario suddenly becomes overpowered and sent hurtling a great distance away. In Super Mario RPG, as Mario goes to free Peach after defeating Bowser, Smithy's gang sends Exor crashing into the castle, the impact sending Mario flying, landing back at his house. In Paper Mario, as Mario is fighting Bowser, Bowser makes himself invincible with the Star Rod, then dispatches Mario out a window, and he crash lands in a field just outside Goomba Village.
 * In both games, Bowser's castle is unreachable throughout most of the story. In Super Mario RPG, it cannot be reached because the bridge is down; in Paper Mario, the castle is up in the sky. Also, both games feature a special vehicle that is used to reach the castle (the Royal Bus and Star Ship, respectively).
 * Mario uses jump and hammer attacks, which in both games have regular, super, and ultra variations. Both have the three hammer variants, but the jump variants in Super Mario RPG are special moves Mario learns, whereas Paper Mario has these variants as the boots Mario finds to improve his jumping ability.
 * The Power Bounce Badge is reminiscent of Mario's Super Jump ability in Super Mario RPG.
 * Mario's first party member in both games has a special move that identifies the enemy (Mallow's "Psychopath" and Goombario's "Tattle").
 * Both games feature a special area where Mario can turn into 8-bit Mario, complete with 8-bit sounds and music.
 * In both games, Mario can travel to an island where Yoshis live.
 * During the second boss battle with Bowser, he can temporarily disable some of Mario's commands, similar to how Bowyer disables certain button commands during his battle in Super Mario RPG.
 * When Lava Piranha re-emerges from the lava after the first phase of the battle, it resembles Czar Dragon's resurrection as Zombone.
 * Both games feature a volcano as a location where a star is hidden. Both areas have an escape sequence after locating the Star, though the reason behind it is different (in Super Mario RPG, the Axem Rangers are escaping with the Star; in Paper Mario, the volcano is erupting).
 * The endings in both games feature a parade that is led by Luigi and ends with a fireworks display.
 * Both Super Mario RPG and Paper Mario feature a Hammer Bro who hosts a quiz game.
 * During the parade in the ending of Paper Mario, Twink flies by with Mario and Peach waving at him on a starlit float, as Geno does in Super Mario RPG.
 * Both games feature antagonist groups that are based on characters from TV series (the Koopa Bros. are based on the, while the Axem Rangers are based on ).
 * In both games, the battle for the sixth star takes place in the sky (the Axem Rangers battle and the Huff N. Puff battle).
 * Both games have a party member who fights against Mario first before joining him (Bowser and Lakilester).
 * Both Super Mario RPG and Paper Mario have three-headed Piranha Plant bosses (Smilax and Lava Piranha).
 * The battle systems of both games contain a feature where correctly timed player input makes the protagonists perform better overall. Super Mario RPG has "timed hits", while Paper Mario has "action commands".
 * Both games feature a sidequest involving helping an artist (Toadofsky in Super Mario RPG and the Master Poet in Paper Mario) complete a piece of music, though the specifics of how they're resolved is different.

References to other games
In addition to its many similarities to Super Mario RPG, Paper Mario has many elements that reference other games:
 * Donkey Kong - The opening theme plays when confronting the Koopa Bros. in Koopa Bros. Fortress, followed by the Koopa Bros. theme. Also, Mario's pixel form's colors is based on his colors from the game's artwork and sprite.
 * Super Mario Bros. - By entering a vase in Boo's Mansion, Mario can assume his appearance from this game's sprites, albeit with the color scheme used for him in the game's artwork. Also, if the player waits fifteen or more seconds when a chapter title is shown on screen, the overworld theme will play. There is a Candy Pop on Pleasant Path which will give free hearts and play the invincibility theme if Mario runs around it. The coloration of Luigi's parade outfit during the credits matches his outfit from this game, including the gold-colored emblem on his cap.
 * Super Mario Bros.: The Lost Levels - The ending theme for the 64th Trivia Quiz-Off has the same beginning notes as the bonus theme from the All-Stars version of this game. Additionally, at the end of the game, when Peach thanks all of the friendly characters for helping restore peace to the Mushroom Kingdom, the music that plays is this game's ending theme.
 * Super Mario Bros. 2 - After saving Luigi from a Shy Guy, he says "I'm a great jumper, but my running needs some work", referencing his higher jumps and lower speed from this game.
 * Super Mario Bros. 3 - Elements from the castle theme is incorporated in the background music for the Koopa Bros. Fortress. When the Koopa Bros. fire Bullet Bills at Mario and his party members, a cover of the Koopalings' Airship theme plays. The Koopa Bros. fight theme is a cover of the Hammer Bros. theme from this game. The level up music is a cover of the overworld theme from World 1. When Mario finds a new hammer or pair of boots, an arrangement of the boss clear theme plays. When Mario rescues a Star Spirit, an arrangement of the "King Saved" theme is played. Another arrangement plays when Mario wins the Star Rod back from Bowser.
 * Dr. Mario - When Mario defeats the Fuzzipede boss, the whale exclaims that "they should call him Dr. Mario!"
 * Super Mario World - The Attack FX E Badge makes the same sound that Yoshi makes when Mario jumps on his back. Also, the main melody for the overworld, underwater, and athletic themes is a cover for Paper Mario's title screen music, with notable modifications. This melody can also be heard during the first half of the parade during the game's ending. The switch theme can be heard as part of the battle music during the fight with Bowser???. The song that plays on the Golden Oldies station of the radio is a cover of the credits theme. The sound effect heard when the player presses Start and brings up the file select is similar to the sound effect for Message Blocks in this game. Lastly, Dry Bones borrow their style and behavior from their Super Mario World iteration, including red shoes and the ability to throw bones at Mario.
 * Super Mario World 2: Yoshi's Island - Bandits (the red kind, that only take coins), Spear Guys, Pyro Guys, a Lantern Ghost, forward-facing Piranha Plants, and Crazee Dayzees appear as enemies. Goombas, Boos, and Chain Chomps use their designs from this game, with the Boos and Chomps closely resembling Bigger Boo's artwork and Chomp Sharks respectively. The Clubbas' face design resemble the Spikes' design from this game, with the White Clubbas closely resembling to them. Sushie's coloration and Squirt attack favor the appearance and abilities of the Spray Fish, Spy Guys wear flowers on their heads like Petal Guys. Stone Chomps appear similar to the brown Chomp Rocks. The music used for Yoshi's Village and when the Fearsome 5 are missing is a cover of this game's title screen music. Little Mousers (being blue based on their in-game sprite and purple based on their artwork), Ravens (including Raphael) and Bumpties (simply called "penguins" in-game) make an appearance as NPCs. Lava Piranha and Kent C. Koopa are similar in appearance to Naval Piranha and Hookbill the Koopa respectively. The final boss battle against Bowser had some similarities to the final boss fight in Yoshi's Island, namely that his right-hand minion enchants Bowser to become larger in order to increase the odds of beating his nemesis (with the only notable difference being that Kamek cast the spell on Bowser directly, while Kammy Koopa merely activated the Power Platform to have Bowser become larger). Poochy, a blue-colored Bandit, and a Nep-Enut appear in one of the game's early builds.
 * Super Mario 64 - Peach's Castle design is similar to that used in this game's box art and is near identical inside, but without the paintings. Both games begin with a letter from Peach. Also, Mario jumps into a painting to access the third floor of Boo's Mansion similar to the way he accessed areas in this game. The Stone Cap is an item based on the powered-up caps and it functions similar to the Metal Cap.
 * Mario Kart 64 - When riding the K64 train, a cover of the Kalimari Desert theme plays. Also, the concept of a train running through a desert and the train itself originates from this game.
 * Mario Golf, Mario Tennis, and Mario Party series - On page 1 of Luigi's Diary, it says, "I remember the carefree days when we played Golf and Tennis and had Parties." The capital letters specifically hint at their respective games.
 * The Legend of Zelda series - If Goombario uses tattle on Sheek after he reveals his true identity, he will start his tattle with "da da da dum", a reference to the "item get" theme from this series. Also, Sheek himself is a reference to Sheik from The Legend of Zelda: Ocarina of Time.
 * Luigi's Mansion - On page 2 of Luigi's Diary, he talks about how much he is afraid of ghosts. On page 7, it says, "I want to play the lead in an adventure! Of course, my name would have to be in the title. That'd be sweet... But I know it'll never happen..." Less than year after Paper Mario, Luigi's Mansion was released for the Nintendo GameCube, with Luigi as the main character tasked with fighting ghosts.

References in later games

 * Mario Kart: Super Circuit - Peach's castle is seen on top of Bowser's castle just like in Paper Mario, located in the background of the course Rainbow Road. The Goombas and Hammer Bros. at the award ceremony use their design from Paper Mario.
 * Mario Party 5 - The Star Spirits return as hosts, but here are named the Star Guards instead.
 * Mario & Luigi: Superstar Saga / Mario & Luigi: Superstar Saga + Bowser's Minions - A block from Paper Mario appears in Woohoo Hooniversity, along with blocks from other games. The name of the game is even mentioned in the block's description.
 * Paper Mario: The Thousand-Year Door - Parakarry makes a brief cameo at the beginning of the game, and delivers a letter to Mario from Peach, just like the previous game. Lady Bow also makes a cameo appearance, and makes a direct reference to Boo's Mansion, as well as the adventure they had. There is also a random Toad at the Excess Express (after Chapter 6 is completed) that will ask Mario a quiz question, ("What did Bowser steal in the first Paper Mario?"), and the answer is, "Star Rod". The videogame-obsessed Toad kid from Petalburg also mentions that he has been playing this game, describing Bow as the "cutest Boo of ALL TIME!!!" Jr. Troopa also appears in the background in the picture that Zip Toad attached to his e-mail. Several parallels exist between bosses in the two games. The first chapter boss in both games resides in a gray fortress, the third chapter boss in both games are members of the Spike species, the fifth chapter boss in both games have "cognizant limbs" and can be found in caves of some sort on tropical islands, and the sixth chapter boss in both games is one entity consisting of multiple, smaller members of their species (and both explode when defeated, releasing the smaller units toward the screen). Additionally, puzzles in some places are solved identically or similarly. The Riddle Tower has many puzzles from Crystal Palace, including walking through or blowing up seemingly solid walls, and the Palace of Shadow has puzzles and traps from Bowser's Castle, including an area wherein Mario only makes progress by following a pattern (though this is actually taken from the final castle level in Super Mario Bros.) and rooms with stairs where Mario has to defeat Bullet Bill Blasters to reach the next level.
 * Mario Pinball Land - Koopatrols appear as enemies in Bowser's castle.
 * Super Mario 64 DS - The Goomba King returns in this game, renamed to Goomboss.
 * Super Princess Peach - Koopatrols appear as statues in Bowser's Villa.
 * Mario Party 7 - The board Pyramid Park has a Bowser Sphinx whose crown has the same colors and Chain Chomp ornament as Tutankoopa's crown.
 * Mario Kart DS - Goomboss also appears in this game's Mission mode.
 * Mario & Luigi: Partners in Time - Star Hill appears once again and is north of the castle just like in this game.
 * Super Paper Mario - Every party member here returns as a Catch Card in this game. Francis also has posters of Lady Bow and Bootler in his castle. Tubba Blubba was also mentioned, and had his own TV show called, "The Blubbening". At the beginning of this game, all of Mario's party members, as well as his ones from Paper Mario: The Thousand-Year Door, are all seen together in a photo. The "chapter parallels" return, though to a lesser extent. For Chapter 3 in both games, Mario travels through a castle with chambers/rooms similar to those of real-world large homes and castles, and both contain security entities that will remove Mario from the area if he is caught. For Chapter 5 in both games, the bosses once again have "cognizant limbs", and both happen to be plant-based.
 * Super Mario Galaxy - Both games begin with a letter from Peach to Mario, also Bowser's way of kidnapping Peach (by lifting her castle into the sky) is reused here.
 * Super Smash Bros. Brawl - Kooper, Lady Bow, General Guy, and Kammy Koopa appear as Stickers. Three of the Star Spirits - Eldstar, Muskular, and Misstar - are also represented by Stickers, but use their Mario Party 5 artworks.
 * Paper Mario: Sticker Star - Similar to Bowser's role in this game, Bowser ends up being the main villain as well as being superpowered by a wish-granting object. Unlike in Paper Mario, however, his gaining the object was completely accidental.
 * Super Smash Bros. for Nintendo 3DS - In the Paper Mario stage, the whale from Chapter 5 appears under the S.S. Flavion variation of the stage lifting the ship up above the water.
 * Paper Mario: Color Splash - When Mario collects a Big Paint Star, an arrangement of the first few notes of this game's title theme is played.
 * Super Smash Bros. Ultimate - Piranha Plant turns into a Putrid Piranha during its Poison Breath move, and spits poisonous gas to damage other fighters. It is also mentioned briefly by Viridi during Palutena's Guidance dialogue for Piranha Plant.
 * Paper Mario: The Origami King - Peach's Castle is once again lifted into the sky, this time placed on top of a volcano.

Development
Paper Mario started development as a sequel to Super Mario RPG: Legend of the Seven Stars and production was initially handled by staff that worked on the game. Ryota Kawade was brought in as the chief director and designer, with Shigeru Miyamoto co-producing the game. Early in development, it was decided to divorce the project from Super Mario RPG and the developers took a year and a half to experiment with character and graphical style ideas, including pre-rendered sprites (like Super Mario RPG) and polygons. Although development was initially done with workstations as with most first-party Nintendo 64 games, the final game's graphics were done with internal Super Famicom tools. Art director Naohiko Aoyama was responsible for creating the series' distinct paper-like style for character graphics, taking inspiration from the graphics of the PlayStation's ' and traditional animated films, such as those in the animation canon or the ' franchise. Aoyama believed that players would prefer a game with "cute" paper-like character designs over one with low-polygon 3D graphics.

The original characters introduced in Super Mario RPG were not featured as the developers felt it was better to stick to "the main road" of the Mario franchise. The story was conceived early in development and the developers decided to focus on making other aspects of the game appealing to all players in the long run rather than making it "about some grand enticing story", especially as it was felt serious and dramatic themes would be at odd with the lighthearted feel of the franchise.

Particular focus was placed on the battle system, its designing taking up about half of the game's production time. As the developers were aware the game would be primarily played by a young audience, the game was balanced around the idea that combat would not be so easy as to be mindless but not so difficult that it would discourage players. The Action Commands were included to appeal to more seasoned players and the Badge system was put in place to simulate the traditional RPG feeling of growing stronger as the game progresses without featuring equipable weapons or a large amount of stats.

The development of Paper Mario took four years, a very long development cycle for the time. Outside of Intelligent Systems, the development involved auxiliary work by uncredited personnel from, , Rare Ltd., and Ubisoft, according to Miyamoto.

Reception
Paper Mario received critical acclaim, with praise directed at its battle system, graphics, and soundtrack. Numerous critics compared Paper Mario to Super Mario RPG: Legend of the Seven Stars, owing to their similar RPG mechanics.

Staff
Paper Mario was developed by Intelligent Systems, an affiliate studio of Nintendo. Shigeru Miyamoto was the game's co-producer, alongside Kenji Miki. Ryota Kawade was the chief director and game designer, with sub-directors including Toshitaka Muramatsu, Takahiro Ōgi, and Hironobu Suzuki. Kumiko Takeda and Kaori Aoki wrote the game's script, while Naohiko Aoyama was the art director and character designer. The programming team was led by Kenji Nakajima and Kaoru Kita. The game's main musical compositions were written by Yuka Tsujiyoko, with event jingles and music-based sound effects written by Taishi Senda, while Koji Kondo was credited as the original composer of themes arranged from previous Mario and Yoshi games.

Pre-release and unused content
Early screenshots of Paper Mario showed that Poochy was originally intended to play some sort of role in the game. Another screenshot showed that Nep-Enuts were going to be in the game (indicating that Lavalava Island was going to be more like Yoshi's Island). Also, a pre-release screenshot of Forever Forest showed that it would have originally been much smaller than it is in the final game, and that all of the forest's trees would have had sinister faces.

Herringway can be morphed into a normal Bumpty or become invisible if the player pauses the game right after Mario and Herringway go into the mayor's room and right before initiating the conversation with the detective during Chapter 7. If invisible, he will reappear when the room is left. If Herringway becomes a normal Bumpty, the game will freeze when the mayor gives him the present. Upon freezing, a debug screen will appear.

Trivia

 * The name "Paper Mario" appears in transcribed form in certain Japanese materials related to this game, including on the back of that region's packaging, despite it not being the title of the game itself there.
 * Paper Mario was released in China on the iQue Player just one month before Paper Mario: The Thousand-Year Door was released in Japan.
 * Paper Mario was the final Mario game released for the Nintendo 64 in Australia, while in the rest of the world, Mario Party 3 was the last Mario game to be released for said console.
 * Several tracks were adjusted between the Japanese and American releases. The theme for Mt. Rugged uses slightly different instruments, and the themes for Bowser's Castle and the final Bowser fight after gaining the Peach Beam have been pitch-corrected. The music played when a party member joins Mario has also been changed, although the credits theme was not adjusted to match.
