'''''Super Mario Galaxy 2''''' is a 3D action [[Genre#Platform games|platform game]] released for the [[Wii]] on May 22, [[list of games by date#2010|2010]]. It is the sequel to the [[list of games by date#2007|2007]] game ''[[Super Mario Galaxy]]'', the thirteenth entry in the ''[[Super Mario (series)|Super Mario]]'' series,<ref name=encyclopedia>Kazuya Sakai (Ambit), kikai, Akinori Sao, Junko Fukuda, Kunio Takayama, and Ko Nakahara ({{wp|Shogakukan}}) (ed.). ''[[Super Mario Bros. Encyclopedia|Encyclopedia Super Mario Bros.]]'' Milwaulkie: [[Dark Horse Comics|Dark Horse Books]], 2018. ISBN: 978-4-09-106569-8</ref> the fourth 3D platformer, and the only 3D platformer in the ''Super Mario'' series to be released on the same console as its predecessor. The sequel retains many elements from its predecessor, such as the adventure being in outer space, the element of [[gravity]], [[list of items|items]] such as the [[Bee Mushroom]] and [[Spring Mushroom]], and recurring objects such as [[Launch Star]]s and [[Sling Star]]s. However, the game introduces new elements as well, such as the utilization of [[Yoshi]], new [[list of power-ups|power-ups]] like the [[Cloud Flower]], and the use of [[Cosmic Spirit|a guide]] within the game for beginner players. All releases of the game except for the American version include a beginner's DVD to help players understand the controls and items if they have not played ''Super Mario Galaxy''. In North America, help for beginners is found on the official website as well as on the [[Wii#Nintendo Channel|Nintendo Channel]].

''Super Mario Galaxy 2'' is also the first Wii title to be digitally re-released on the [[Wii U]]'s [[Nintendo eShop#Wii U|Nintendo eShop]] service.
==Story==
'''''From the instruction booklet'''''
<blockquote>Shining stardust falls on the Mushroom Kingdom once every hundred years. That time had come again...

:Dear Mario,

:Would you like to share some cake while we watch the shooting stars? Meet me at the castle!

::Peach

Mario ran through the field with stars falling around him. Suddenly, he noticed a strange light in the grass. As he peered cautiously through the reeds, he saw a small, lost Luma. With the baby Luma tucked safely under his cap, Mario rushed on to the castle. But when he got there, something unexpected was waiting for him…</blockquote>
[[File:SMG2 Prologue2.png|thumb|left|upright=1.1|[[Giant Bowser|Super Bowser]]]]
''Super Mario Galaxy 2'' is "another story of stardust".<ref>[https://web.archive.org/web/20190209092340/https://www.nintendo.co.jp/character/mario/collection/search.html Mario Portal (Japanese)]. ''Nintendo''. Retrieved August 19, 2018.</ref> The game begins at the time of the [[Star Festival]], which only happens every 100 years. [[Princess Peach]] invites [[Mario]] to share some [[cake]] while watching the shooting stars. On his way to Peach's Castle, Mario finds a lost [[Baby Luma]], who seems to like Mario and jumps into his hat, granting him [[spin]] power. Near the castle, Mario discovers it under attack by [[Bowser]], now [[Giant Bowser|gigantic]] thanks to the Power Stars, who kidnaps Peach and takes her away to the center of the universe. In response, [[Luma]]s who crashed near the castle offer to aid Mario to chase Bowser by transforming into a [[Launch Star]] and launching Mario to space.

After collecting a Power Star, Mario arrives on a planet-like object, where he meets [[Lubba]], who tells him that his crew and their spaceship were attacked by Bowser. Realizing both him and Mario need each others' help to collect the stolen Power Stars and rescue Peach, he uses the Power Star to fix his ship and transform it into [[Starship Mario]], which is used to travel through space and find more Power Stars. During his travels, Mario has to deal with Bowser's forces, including [[Bowser Jr.]] and Super Bowser himself.

[[File:SMG2MarioLuma.png|200px|left|thumb|Baby Luma bidding farewell to Mario and Peach.]]
Finally, Mario and friends locate [[Bowser's Galaxy Generator]], where Bowser is fought for the final time. After Bowser's defeat, his empire becomes undone, and Peach is saved. A comet which was caught by Bowser's fortress is also freed and is revealed to be the [[Comet Observatory]]. [[Rosalina]] then appears, happy to see that Baby Luma is safe. Baby Luma, overjoyed that he's reunited with his "mama", heads back to his home, and takes [[Mario Cap|Mario's cap]] as a souvenir, much to Mario's surprise. After the Comet Observatory leaves, Mario and Peach return to their own home using the Starship Mario. Along the way, Bowser is shown in a tiny form near Peach's Castle.

[[File:SMG2Rosalina.png|200px|thumb|[[Rosalina]] telling stories to the Lumas.]]
If the player collects the first 120 Power Stars and battles Bowser again in his fortress, an extra scene is shown after the credits, revealing Rosalina and her Lumas in the Comet Observatory's Library. She has finished reading a story to them (possibly the events of the game itself) and plans on telling the Lumas a new story about the [[Green Power Star]]s. A new feature is then unlocked in which all the galaxies are visited by green Prankster Comets. From there, the player must hunt down all the Green Stars. When they are all collected (adding up to 240 Power Stars), the [[Grandmaster Galaxy]] is opened in World S. It houses the last two Power Stars, and when the last one is reached, Rosalina congratulates the player and appears on [[Starship Mario]].

==Gameplay elements==
[[File:SMG2 Starship Mario Screenshot.png|thumb|left|upright=1.1|Mario on the deck of Starship Mario.]]
The gameplay is similar to ''[[Super Mario Galaxy]]'', with a focus on platforming based on and around 3D planets of varying sizes and with many different types of surfaces. Power-ups, such as the [[Bee Mushroom]], [[Boo Mushroom]], [[Spring Mushroom]], and [[Fire Flower]] make a return, along with new ones such as the [[Rock Mushroom]] and the [[Cloud Flower]], as well as various enemies and [[Airship]]s. [[Launch Star]]s reappear for interplanetary navigation, along with a [[Baby Luma|Luma]] and [[Mario]]'s [[spin]] action. Additionally, the concept of "dark matter" appears as the medium of which [[Cosmic Clone]]s are composed, and as a portal through which Airships emerge. 2-D stages featured in ''Super Mario Galaxy'' are also included in ''Super Mario Galaxy 2'', introducing many new features. The game has only three file slots to use, unlike the six files in the preceding game; also, files can no longer be copied.

Mario is controlled with the analog stick and can jump with the {{button|wii|A}}. The {{button|wii|Z}} works just as the {{button|n64|Z}} trigger did in ''Super Mario 64''. The player uses it to make Mario crouch, do [[Somersault]]s, and do [[Long Jump]]s. The {{button|wii|C}} centers the camera behind Mario, while the {{button|wii|Pad}} can adjust the camera angle manually. By pressing the upper part of the {{button|wii|Pad}}, the player can enter a first-person perspective.

The game also uses the motion sensors in the Wii Remote. The pointer of the Remote appears as the [[Star Pointer]] on the screen. The Star Pointer is used to perform a variety of actions, such as using [[Pull Star]]s, manipulating [[Sling Pod]]s, and collecting [[Star Bit]]s. Shaking the [[Wii#Wii Remote|Wii Remote]] or [[Wii#Nunchuk|Nunchuk]] makes Mario perform a [[spin]]. 

[[File:Luigi yoshi.png|thumb|upright=1.1|[[Luigi]] and [[Yoshi]] about to get a [[Blimp Fruit]] in [[Starshine Beach Galaxy]].]]
One of the more notable additions in ''Super Mario Galaxy 2'' is the inclusion of [[Yoshi (species)|Yoshi]]. When Mario finds a [[Yoshi's Egg|Yoshi egg]], he can crack it to release and use Yoshi. Yoshi changes colors when eating either a [[Dash Pepper]], [[Blimp Fruit]] or [[Bulb Berry]]; a [[Dash Yoshi]] darts at rapid speeds, a [[Blimp Yoshi]] inflates and floats upwards, and a [[Bulb Yoshi]] lights up and shows hidden paths for a certain amount of time, respectively. When utilizing Yoshi, the player's Wii Remote cursor turns into a red sphere that detects targets for Yoshi's tongue. Using the cursor allows Yoshi to swallow enemies and swing from special flowers.

Elements from older games are also included in the new game. These elements include a remix of ''[[Super Mario Bros.]]''{{'}}s overworld theme (which is originally heard in [[Toy Time Galaxy]] from the predecessor, ''Super Mario Galaxy''), [[Supermassive Galaxy]], a galaxy that is reminiscent of [[Giant Land]] from ''[[Super Mario Bros. 3]]'', a remix of the second overworld theme from ''[[Super Mario World]]'', the [[Checkpoint Flag]] from ''[[New Super Mario Bros. Wii]]'', [[Throwback Galaxy]], a galaxy based on [[Whomp's Fortress]] from ''[[Super Mario 64]]'', and a remix of the main theme and slide theme from ''Super Mario 64''.

[[File:SMG2 CosmicCoveGalaxy.png|thumb|left|upright=1.1|Mario and Co-Star Luma on the underwater portion of [[Cosmic Cove Galaxy]].]]
[[File:SMG2 Portal.png|thumb|upright=1.1|Mario near the [[Portal]] leading to [[World 4 (Super Mario Galaxy 2)|World 4]].]]
Like ''Super Mario Galaxy'', ''Super Mario Galaxy 2'' features a main hub. For traveling between different galaxies, Mario uses a planet shaped like his head, [[Starship Mario]]. Starship Mario can be explored, much like the Comet Observatory, although it is smaller. The game has a total of 242 stars to collect, twice the number of stars found in ''Super Mario Galaxy'', including 120 [[Power Star]]s, 120 [[Green Power Star]]s and an extra 2 Power Stars in [[Grandmaster Galaxy]].

Multiplayer from the original ''Super Mario Galaxy'' reappears, but in addition to being another star pointer, the second player is a [[Co-Star Luma]]. The second player can stun enemies and pick up Star Bits like in ''Super Mario Galaxy'', but now they can pick up coins (including [[Purple Coin]]s) and mushrooms, defeat enemies by spinning, stop the [[Star Ball]] (while player 1 is riding on it), activate checkpoints, and flip switches.

[[File:Cosmic Guide mode.png|thumb|upright=1.1|Mario in the Cosmic Guide mode of [[Flip-Swap Galaxy]].]]
''Super Mario Galaxy 2'' features ways to help players during gameplay similar to the Super Guide mode seen in ''[[New Super Mario Bros. Wii]]''. In some levels, the player may watch the [[Tip Network]], which is a short demonstration of Mario taking some actions to progress. Another way the game offers is the Cosmic Guide mode. If the player finds a very difficult obstacle on their way, an entity known as the [[Cosmic Spirit]] asks Mario if he needs some help. Activating this mode, Mario passes automatically through the level to find the Star. The player may stop this mode by pressing the {{button|wii|+}}, though once the player has chosen this mode, they finish a level by getting a [[Bronze Star]] instead of one gold. The player must play through the level without the Cosmic Guide to gain a gold Star. 

Unlike in ''Super Mario Galaxy'', the player can now switch between playing as Mario or playing as [[Luigi]] in certain levels. If the player clears [[Bowser's Galaxy Generator]], Luigi can be played as in any level. Like in most ''Super Mario'' games, Luigi can jump higher but has reduced traction.

''Super Mario Galaxy 2'' is set in [[Space|outer space]]. With the exception of the prologue that is staged in the [[Mushroom Kingdom]], all levels – referred to as "galaxies" in this game – occur on distant, off-world lands. A galaxy is a cluster of planetary objects and other celestial bodies that can be traveled between. Most of these objects have their own [[Gravity|gravitational pull]]. This prevents [[Mario]] from falling off their edge and mitigates the chances of the player getting lost.<ref name=jasper>Michael `Jasper` Ashworth. "[https://youtu.be/QLH_0T_xv3I How Spherical Planets Bent the Rules in Super Mario Galaxy]". [https://www.youtube.com/ ''YouTube'']. Published 29 Sep 2020.

[https://web.archive.org/web/20071028080149/http://www.sijm.ca/ ''Montreal International Games Summit''] (archived), Jan. 2007. Recorded by [https://www.youtube.com/channel/UCDPIKeNz3vl-nwayZ-r0POA Eric St-Cyr]. Compiled by [https://www.youtube.com/channel/UC1rayIrkZu7ssVkTTa89oPA Hover]. [https://www.youtube.com/ ''YouTube'']. Published 24 Sep 2016. Accessed 27 Feb 2021.</ref> There are few walls or ceilings on the planets to obstruct Mario's path, and if he keeps moving forward in one direction, he returns to his starting position. Most planets are spherical or at least have rounded edges to complement this concept. Not all planets are structured like this: some are structured like traditional ''[[Super Mario (series)|Super Mario]]'' courses and have their center of gravity below their mass.

Many galaxies take place on two-dimensional planes and Mario's movement options are restricted accordingly (i.e. when Mario is on a 2D side-scrolling plane, the player cannot tilt {{button|wii|Stick}} towards the z-axis to make him fall off the side). There are galaxies entirely on 2D planes, but also ones that feature both 2D and traditional 3D segments. They are usually restricted to specific planets and conveyed through environmental context. Many galaxies feature switches mounted into the landscape that change the entire level when interacted with. Some shift between the gravity being pulled from the floor and ceiling. Others slow down time, or shift placement when Mario spins.

The theme of space is more subdued in ''Super Mario Galaxy 2'' than it is in [[Super Mario Galaxy|its predecessor]]. While there are galaxies that feature skyboxes with nebulas and stars, the most recurring backdrop is a blue sky with fluffy clouds. However, the game does convey the outer space setting in ways distinct from the first ''Super Mario Galaxy''. As [[Starship Mario]], the game's hub, travels through space, it passes asteroid belts, falling stars, and [[black hole]]s. [[Luma]]s, star children introduced in its predecessor, appear in nearly all galaxies and on the hub. The game's thematic core is surreal and whimsical. Rather than resemble a spacecraft, the hub is a grassy planetoid shaped like Mario's head and has a wooden bow like a seafaring vessel. [[Gull]]s fly alongside the ship, as if it were on the open ocean. The whole game is framed from the perspective of an [[Rosalina|unseen narrator]] reading a storybook to the player, and many locations have {{wp|Lewis Carroll|Carrollian}} elements. A pair of [[Gearmo|robots]] have tea together in a garden on Starship Mario. Several galaxies resemble topiaries and dollhouses. Some planets look like wooden blocks, candies, clouds, and musical instruments.

According to producer [[Shigeru Miyamoto]], the integration of 2D levels derived from a desire to make ''Super Mario Galaxy 2'' more accessible and less daunting to players inexperienced with 3D platformers. Integration of elaborate switch elements bore from the desire to differentiate ''Super Mario Galaxy 2'' from its predecessor similarly to how ''{{iw|zeldawiki|The Legend of Zelda: Majora's Mask}}'' (2000) was differentiated from ''{{iw|zeldawiki:The Legend of Zelda: Ocarina of Time}}'' (1998).<ref name=iwata>[[Satoru Iwata]] (trans.

Published 2010. Accessed 12 Apr 2021.</ref> Many elements not present in the first ''Super Mario Galaxy '' informed the setting of the courses that feature them. For example, the first galaxy to feature the [[Spin Drill]] item, [[Spin-Dig Galaxy]], visually alludes to construction sites and has enemies that tunnel through soil.<ref name=wired>Chris Kohler.

The former offers more unilateral progression, with the completion of a mission in one galaxy only granting the player access to one or two new galaxies. In World 5, completing Space Storm Galaxy immediately grants one access to four new galaxies that they can play in any order they choose.

In ''Super Mario Galaxy 2'', levels are accessed linearly within [[world]]s. This is a departure from the proceeding 3D ''[[Super Mario (series)|Super Mario]]'' games and is comparable to the 2D ones. The player accesses worlds from the [[Starship Mario]], a small planetoid that serves as the game's hub. When Mario steps on a panel on the starship's bow, the perspective rapidly pans out to a view of the current world. Starship Mario – itself shaped like the protagonist's head – is a stand-in for Mario himself that can be moved between galaxies like a cursor. Galaxies are unlocked unilaterally – collecting a Power Star within one opens up paths to the nearest galaxies. Except for [[World S]], the final galaxy of each world is a boss galaxy that features a fight against [[Bowser Jr.]] or [[Giant Bowser|Bowser]]. Defeating them unlocks the following world. The earliest worlds have the simplest, most straightforward paths between galaxies, but the paths become more divergent with each world, enabling the player to visit galaxies in whatever order they want (see right).

Unlike proceeding games that feature worlds – like ''[[Super Mario Bros. 3]]'' (1988) and ''[[New Super Mario Bros.]]'' (2006) – the galaxies within the worlds of ''Super Mario Galaxy 2'' are not thematically unified. For example, [[World 3 (Super Mario Galaxy 2)|World 3]] contains galaxies themed around forests, snow, and haunted houses. While not all galaxies need to be completed, no numbered worlds can be skipped over to reach the end credits.

Each galaxy contains objectives called [[mission]]s. Completing a mission has [[Mario]] obtaining one of the galaxy's [[Power Star]]s. One mission correlates with one Power Star. The structure of missions is closely derived from the first ''[[Super Mario Galaxy]]'' (2007). However, there are fewer dedicated missions in individual galaxies, with none having more than three. By contrast, the most robust galaxies in ''Super Mario Galaxy'' have as many as six missions. Some missions have one or more hidden [[Green Star]]s that begin to appear once the player has collected 120 normal Power Stars. Like regular Power Stars, collecting one is considered as the end of the mission. [[Grandmaster Galaxy]] is the only course in the game to lack any Green Stars. Combined, there are 242 collectible Stars in the game, the same number in its predecessor.

Some galaxies can only be unlocked by feeding [[Hungry Luma]]s a requested number of [[Star Bit]]s. They appear on the world map and transport to the Starship Mario when touched. There is one in every world. Hungry Lumas appear within galaxies too, but these individuals eat coins instead of Star Bits. Feeding one the requested amount causes it to transform into a planet that contains a Secret Star. Secret Star missions are otherwise unlocked by completing certain criteria. Doing so causes non-playable characters to write letters to Mario requesting his help or to challenge him in specific galaxies he has already visited at least once. The most recurring writer is [[The Chimp]], a monkey from [[Fluffy Bluff Galaxy]] who considers Mario to be his rival.

After Mario has completed "[[Bowser's Big Lava Power Party]]" and collects three Power Stars from [[World 3 (Super Mario Galaxy 2)|World 3]], his brother [[Luigi]] begins to appear in some galaxies and offer to collect the Power Star for him. Selecting "yes" allows the player to control Luigi for the mission until it is completed or exited. Completing the mission as Luigi unlocks a [[Ghost (Super Mario Galaxy 2)|staff ghost]] for the galaxy. When followed, it leads the player towards hidden items or Secret Stars. Once "[[Bowser's Fortified Fortress]]" is completed, Luigi becomes permanently accessible via a room on Starship Mario's stern and can be played as in any level.

''Super Mario Galaxy 2'' is the first 3D ''Super Mario'' game to include a dedicated secret world accessible only after completing the main story, similar to the [[Special Zone]] of ''[[Super Mario World]]'' (1990) or [[World 9 (New Super Mario Bros. Wii)|World 9]] of ''[[New Super Mario Bros. Wii]]'' (2009). Called World S, this world contains several galaxies based around planets from the first ''Super Mario Galaxy'' that have been modified in ways that make them more challenging.

There are 49 galaxies in the game, 50 if Starship Mario is included. The chart below lists the galaxies in the order that they appear on the [[Star List]]. The galaxies are separated and color-coded according to the world they occur in. Each galaxy is given a brief description, an in-game screenshot, and a list of its missions. The descriptions come from the official [[Prima Games]] guide for ''Super Mario Galaxy 2''.<ref>Catherine Browne. ''Super Mario Galaxy 2: Prima Official Game Guide''. Roseville: Random House Inc, 2010. ISBN: 978-0-30746-907-6.</ref> There is a legend at the bottom of the chart that details what the symbols used in it represent.

===Prankster Comets===
{{main|Prankster Comet}}
[[Comet Medal]]s are collectibles hidden in galaxies. Every galaxy has a Comet Medal. Collecting one adds it to the player's total, much like Power Stars, Star Bits, and coins. If Mario loses a life after collecting one and finishes the mission, the Comet Medal will not be added to his total. He will have to return to a mission in that galaxy to collect it again. Accumulating Comet Medals causes Prankster Comets to orbit previously visited galaxies. The comets unlock new missions in their corresponding galaxies with unique attributes, namely speed runs; "daredevil" runs (in which Mario is defeated if he takes a single hit); [[Purple Coin]] runs; races against [[Cosmic Clone]]s; romps requiring Mario to defeat 30 enemies within a time limit; and missions where the speed of obstacles is increased. Not every galaxy can be orbited by these types of Prankster Comets. After completing all 120 missions and completing "[[Bowser's Fortified Fortress]]" a second time, Green Comets begin orbiting every galaxy except for Grandmaster Galaxy. This causes hidden [[Green Star]]s to appear in previously completed missions.

Prankster Comets were an element in the game's [[Super Mario Galaxy|predecessor]], but their integration has been simplified in ''Super Mario Galaxy 2''. Additionally, unlike in the prior game, Prankster Comets permanently remain in orbit around their corresponding galaxies, allowing the player to access the new missions at any time they wish.

===Starship Mario===
{{main|Starship Mario}}
[[File:SMG2 Starship Mario Engine Room.png|x120px|thumb||right|Screenshot of the Engine Room. The display of power-ups is one of the ways that progress is passively tracked.]]
[[File:SSBU Starship Mario Spirit.png|right|145px]]
The Starship Mario is the hub of the game. It is a planetoid-turned-spaceship created by [[Lubba]] as a home for his [[Luma]]s. After becoming acquainted with [[Mario]], he transforms it into his likeness. Rather than invoke a spaceship design comparable to those in science fiction, the Starship Mario has a fantastical design: it has a bow like a seafaring vessel, a stone chimney, and is flocked by sea gulls. It is covered in flowers and has a small brook. It has two accessible rooms: one is the Engine Room that houses the [[beacon]] – the source of energy for Starship Mario. The other is a pipe room occupied by Lumalees accessible via a [[pipe]] in the starship's left ear. It only appears after Mario has collected a Power Star in [[World 3]]. The bow of Starship Mario has a button before a steering wheel that allows the player to access the [[world]] map and move the starship like a cursor. After collecting sixteen Power Stars, Lubba places a Totals Sign to the left of the helm that outlines all of the Power Stars and Comet Medals that the player has collected. Lubba himself is to the right.

A grassy platform with [[fruit (Yoshi food)|fruit]]s begins orbiting the starship after completing "[[Saddle Up with Yoshi]]", and a [[Starshroom]] bearing members of the [[Toad Brigade]] flies with it after completing "[[Digga-Leg's Planet]]".

In ''[[Super Mario Sunshine]]'' and ''Super Mario Galaxy'', completing missions would cause portions of their respective hub worlds to become illuminated. This gave the player a passive visual indication of progress and an indicator as to where one can go. In ''Super Mario Galaxy 2'', this is instead achieved by filling up the Engine Room and in having non-playable characters board the Starship Mario as passengers. The Engine Room is accessible under the stone brim of the starship's cap. Most power-ups will be put on display here after Mario has encountered it in a mission. The only exceptions are the [[Cloud Flower]] and [[Yoshi's Egg|Yoshi egg]], which instead appear on the exterior of Starship Mario and can actually be used. The power-ups in the Engine Room are only for display. The [[Spin Drill]] is among them despite functioning as a held item.

The passengers that board the Starship Mario represent the various people and characters encountered in the galaxies. Some passengers will board once they are met in a mission, but others have more specific criteria required (see below). The more the player completes of the game, the livelier the Starship Mario becomes with characters and the more elaborate its music becomes – elements shared with the [[Comet Observatory]] in ''Super Mario Galaxy''. The passengers will share tricks on level progression or actions when prompted. Some allude to late-game secrets. The last passenger – [[Rosalina]] – is the final unlockable of the game. [[Pianta]]s are the only people to not have a representative on the Starship Mario. The passengers and the criteria needed for them to board is outlined below.

An invitation to [[Peach's Castle]] turns tragic when she is kidnapped by [[Bowser]] and taken into the depths of space. After encountering a group of star children called [[Luma]]s and their leader, [[Lubba]], Mario embarks on a journey through space to collect [[Power Star]]s, stop Bowser, and rescue the princess. This is accomplished through the aid of [[Starship Mario]], a spaceship designed after Mario's likeness, and an [[Baby Luma|apricot-colored Luma]]. The game's story is partially framed as a retelling of [[Super Mario Galaxy|its predecessor]], and Mario similarly has the same {{wp|Game feel|feel}}, physics, and control from the previous game.

This causes Luigi to skid as he moves, and increases the risk of him falling off of a platform or colliding with an obstacle. Luigi is periodically encountered at the start of various missions after Mario has cleared "[[Bowser's Big Lava Power Party]]" and collects 3 Power Stars in [[World 3 (Super Mario Galaxy 2)|World 3]]. He offers to swap places with Mario for the mission when prompted, allowing the player to temporarily control him. After "[[Bowser's Fortified Fortress]]" is cleared, Luigi becomes permanently available and can be swapped with Mario by entering a door beneath the stern of Starship Mario.

Once in agreement, Lubba reshapes the starship into Mario's likeness and starts to affectionately call him "captain". Lubba reacts to the player's actions in-game even though he remains on Starship Mario.

===Bosses===
Bosses are listed in the order that they are first encountered. They are organized into two categories: "main bosses" that are encountered in normal [[mission]]s during the course of the game, and "secret bosses" only encountered through intramissionary Secret Star-missions and in [[World S]], which becomes available after completing the narrative objective of rescuing [[Princess Peach]]. Excluding [[Bowser]] and [[Bowser Jr.]], who are each fought in a completely different fashion from the previous game, six of the game's bosses first appeared in the original ''[[Super Mario Galaxy]]''.

|align=center style="background:#FFFFFF"|[[File:PowerstarSMG.png|100x100px]]<br>[[Power Star]]s
|Objects that are a source of energy for the [[Starship Mario]]. They are stolen by [[Bowser]] to create a galaxy of his own at the [[Bowser's Galaxy Generator|center of the universe]]. Collecting them completes missions and unlocks new levels.
|align=center style="background:#FFFFFF"|[[File:Greenstar.png|100x100px]]<br>[[Green Star]]s
|Hidden, intermissionary Power Stars. Green Stars begin to appear in the galaxies after [[Mario]]<ref name="Luigi" group="note"/> has accumulated 120 yellow Power Stars. Rather than appear in dedicated missions, they are hidden in previously completed ones. One emits a jingling sound when nearby, hinting at its location. Collecting one completes the mission. [[Grandmaster Galaxy]] is the only galaxy to not have any Green Stars. The [[The Perfect Run|final mission]] is unlocked once all 120 Green Stars have been collected.
|-
|align=center style="background:#FFFFFF"|[[File:Bronze star.png|100x100px]]<br>[[Bronze Star]]s
|Embronzed Power Stars and Grand Stars. These replace the normal yellow Power Stars if the [[Cosmic Spirit]] was used to complete a level. A Bronze Star contributes to the player's accumulated star total, but they are not able to unlock Grandmaster Galaxy. To do so requires completing every single level without the Cosmic Spirit's aide.
|align=center style="background:#FFFFFF"|[[File:Silver Star Artwork - Super Mario Galaxy 2.png|100x100px]]<br>[[Silver Star]]s
|Small Stars that represent one-fifth of a Power Star and are contained in [[bubble]]s. Silver Stars squeal like Lumas and trail after Mario when he pops their bubbles. When five are collected, they merge to form a full Power Star.
|-
|align=center style="background:#FFFFFF"|[[File:Grand Star Artwork - Super Mario Galaxy 2.png|100x100px]]<br>[[Grand Star]]s
|Giant Power Stars of considerable energy. They are usually in the possession of bosses. Collecting them creates a [[portal]] through "space and time" that enables the [[Starship Mario]] to travel to new [[world]]s.
|align=center style="background:#FFFFFF"|[[File:CometMetal.png|100x100px]]<br>[[Comet Medal]]s
|Large octagonal coins hidden in many galaxies. Collecting Comet Medals increases the odds of galaxies being orbited by [[Prankster Comet]]s. Like Power Stars, coins, and Star Bits, Comet Medals are a permanent collectible that do not respawn after being accumulated.
|-
|align=center style="background:#FFFFFF"|[[File:StarBits.png|100x100px]]<br>[[Star Bit]]s
|Colorful objects that are eaten by [[Luma]]s. They are found floating in space or raining from the sky. They are collected when Mario makes physical contact or when they are touched with the [[Star Pointer]]. The Star Pointer works like a {{wp|reticle}}: pressing {{button|wii|B}} shoots a Star Bit at its on-screen positioning. Most enemies are stunned when struck by Star Bits. Shooting an idle [[Yoshi]] causes him to run off. Holding {{button|wii|B}} makes Star Bits fire continuously. Fired Star Bits cannot be recovered. [[Hungry Luma]]s encountered on the world map transform into galaxies when fed a requested number of Star Bits. Mario does not lose accumulated Star Bits if he loses a life during a mission, and they are added to his total when he returns to the Starship Mario. Collecting 100 Star Bits gives Mario an extra life.
|align=center style="background:#FFFFFF"|[[File:SMG Asset Model Coin.png|100x100px]]<br>[[Coin]]s
|Gold coins. Collecting one restores one bar to Mario's life meter. Collecting 100 during a mission and returning to Starship Mario gives Mario an extra life. If Mario loses a life during a mission, he loses all of the coins he collected within that specific mission. Hungry Lumas encountered in galaxies will transform into new planets and unlock a secret mission when fed a specified number of coins.
|-

|Coins that only appear in a galaxy when [[Prankster Comet#Purple Comet|Purple Comet]]s are in orbit. Missions involving Purple Coins are [[Time Limit|timed]]: collecting 100 Purple Coins pauses the timer and awards Mario a Power Star.
|align=center style="background:#FFFFFF"|[[File:SMG Asset Model Question Coin.png|100x100px]]<br>[[? Coin]]s
|Big coins with inconsistent properties. Making contact with one has different results depending on the level, but exactly what is not specified until it is touched. One can make a power-up, mushroom, note, or another ? Coin appear. They do not contribute to Mario's coin count.
|-
|align=center style="background:#FFFFFF"|[[File:SMG Asset Model Note.gif|100x100px]]<br>[[Note]]s
|Music notes which can appear when Mario touches a ? Coin or uses a Ground-Pound Switch. They appear in trails in the immediate vicinity and disappear after a few seconds. Collecting every note before they disappear awards Mario with a power-up, a mushroom, or a Power Star.
|align=center style="background:#FFFFFF"|[[File:SMG2 Artwork + Clock.png|100x100px]]<br>[[+ Clock|Clock]]s
|Clocks that only appear in galaxies when [[Prankster Comet#Purple Comet|Speedy Comets]] are in orbit. Collecting one adds 10 seconds to the player's time limit.

|Shells of green [[Koopa Troopa]]s. Mario grabs one when he makes contact or [[spin]]s near it. Shaking {{button|wii|wiimote}} makes Mario throw it. Green Koopa Shells travel in a continuous forward trajectory and defeats enemies on contact. Holding a Shell while underwater makes Mario automatically propel forward at a faster speed than if he were to swim. A light emits from the front of the shell when underwater that helps orient the player. This light can defeat [[Snoodle]]s.
|align=center style="background:#FFFFFF"|[[File:SpinDrill.png|100x100px]]<br>[[Spin Drill]]s
|A drill that can be carried by Mario. Shaking {{button|wii|wiimote}} causes Mario to tunnel through the earth and break through the other side if unobstructed. If Mario strikes an impenetrable obstacle he is launched back the way he came. Some moves become unusable to Mario when he holds a Spin Drill, and he loses it when he is damaged by an enemy or uses a Launch Star. It is required to damage the boss [[Digga-Leg]].
|-
|align=center style="background:#FFFFFF"|[[File:SMG Asset Model 1-Up Mushroom.png|100x100px]]<br>[[1-Up Mushroom]]s
|Green mushrooms that give Mario an [[extra life]] when obtained. They are also sold at the [[Lumalee|Luma Shop]].
|align=center style="background:#FFFFFF"|[[File:SMG Lifeshroom Sprite.png|100x100px]]<br>[[Life Mushroom]]s
|Red mushrooms that doubles the amount of bars in Mario's [[Health Meter|life meter]] from three to six. If Mario loses three bars, they cannot be restored. The life meter returns to just three bars when Mario completes the mission, even if at full health. This mushroom is sold at the Luma Shop.
|-
|align=center style="background:#FFFFFF"|[[File:SMG2 Coin Bubble.png|100x100px]]<br>[[Bubble]]s

|align=center style="background:#FFFFFF"|[[File:SMG2 Artwork Yoshi's Egg.png|100x100px]]<br>[[Yoshi's Egg|Yoshi egg]]s
|The nested egg that holds Yoshi. Spinning into it releases Yoshi from the egg. Sometimes there are multiple Yoshi eggs in a galaxy, but they all disappear once Yoshi is released from one. If Mario is knocked-off of Yoshi, he will panic for a few seconds before being resealed into the egg and transported back to a nest.
|-
|align=center style="background:#FFFFFF"|[[File:SMG2 Artwork Berry.png|100x100px]]<br>[[Fruit (Yoshi food)|Fruits]]
|Ground fruits eaten by Yoshi. Eating one releases a Star Bit. Eating ten gives Mario an extra life. When off of Yoshi, Mario can break a fruit by ground-pounding it.

|The Cloud Flower transforms [[Mario]] into Cloud Mario, which enables him to walk on [[cloud]]s that he would otherwise be too heavy to stand on. Cloud Mario can also create up to three cloud platforms by shaking {{button|wii|wiimote}}, but these platforms will disappear after a brief time. Mario's weight is reduced while Cloud Mario. Receiving damage or making contact with water makes Mario lose the power-up.

|align=center style="background:#FFFFFF"|[[File:SMG2 Artwork Rock Mario.png|110x110px]]<br>[[Rock Mario]]
|Touching the Rock Mushroom transforms Mario into Rock Mario. Shaking {{button|wii|wiimote}} causes him to morph into a [[boulder]] and roll, defeating most enemies on contact and breaking objects Mario would otherwise be unable to. Colliding with an object or wall causes Mario to stop rolling. The boss [[Rollodillo]] can only be damaged by Rock Mario. Receiving damage or using a Launch Star makes Mario lose the power-up.

|Touching the Bee Mushroom transforms Mario into Bee Mario. Holding {{button|wii|A}} makes Mario hover and his movement is controlled by tilting {{button|wii|stick}}. The [[:File:SMG Bee Mario Fly Meter.png|Flying Meter]] depletes as Mario hovers. He falls when the Meter is empty, but it is refilled when he makes contact with the ground or wall. Bee Mario can cling to [[honey wall]]s and stand on [[Flower (platform)|flower]]s. The radius of the [[spin]] move is reduced while Bee Mario. Receiving damage or making contact with water makes Mario lose the power-up.

|align=center style="background:#FFFFFF"|[[File:Rainbow Mario - Super Mario Galaxy.png|x90px]]<br>[[Rainbow Mario]]
|Making contact with the Rainbow Star transforms Mario into Rainbow Mario for thirty seconds. He is invincible and can defeat enemies on contact. [[Run]]ning in this form makes Mario build speed and shortens the height of his [[jump]]. Attempting to collect a different power-up in this form will instead launch it up without collecting it.
|-
|align=center style="background:#FFFFFF"|[[File:SMG Asset Model Boo Mushroom.png|100x100px]]<br>[[Boo Mushroom]]
|align=center style="background:#FFFFFF"|[[File:Boo Mario Super Mario Galaxy 2.png|110x110px]]<br>[[Boo Mario]]

|align=center style="background:#FFFFFF"|[[File:Spring Mario Art - Super Mario Galaxy.png|110x110px]]<br>[[Spring Mario]]
|Making contact with the Spring Mushroom transforms Mario into Spring Mario. Mario continuously jumps in this form. Pressing {{button|wii|A}} when he strikes the ground makes Spring Mario jump to a significantly great height. His horizontal movement is slowed in this state. The Spring Mushroom only appears in "[[Spring into the Chompworks]]". Receiving damage strips Mario of the power-up.
|}

===Yoshi's fruits===
There are fruits that function as power-ups for [[Yoshi]]. When consumed, he is temporarily transformed and gains new abilities.

|align=center style="background:#FFFFFF"|[[File:Blimp Yoshi Art - Super Mario Galaxy 2.png|110x110px]]<br>[[Blimp Yoshi]]
|The Blimp Fruit transforms Yoshi into [[Blimp Yoshi]]. He inflated like a balloon and trickles out air from his mouth, causing Blimp Yoshi to slowly rise. His trajectory can be controlled by tilting {{button|wii|stick}}. Yoshi returns to normal once the air meter is depleted, but its depletion can be slowed by holding {{button|wii|A}}. Doing so also keeps Blimp Yoshi from ascending. Yoshi also can return to normal by shaking {{button|wii|wiimote}}.
|-

|align=center style="background:#FFFFFF"|[[File:SMG2 Artwork Bulb Yoshi.png|110x110px]]<br>[[Bulb Yoshi]]
|The Bulb Berry causes Yoshi to illuminate light as [[Bulb Yoshi]]. The light exposes platforms that would otherwise be hidden and enables the player to use them. This form only lasts for only ten seconds, and the radius of Bulb Yoshi's light gradually depletes. The platforms disappear and can no longer be used once the ten seconds have passed. Eating another Bulb Berry before the time has ran out restores Bulb Yoshi's light and resets the timer.

==Differences from ''Super Mario Galaxy''==
===Gameplay===
*While swimming underwater, Mario and Luigi can no longer spin rapidly.
*An exploit that allowed Mario to climb up slopes was patched.
*The game now saves automatically instead of the player having to manually save after every Power Star collected.
*If the player gets a Game Over, they return to the hub world, rather than being asked to save before going all the way back to the title screen.
*There are only three save files instead of six.
**Rosalina and Luma are new save file icons, while Luigi's can be used as an icon from the start.
**The player cannot copy save files like in the previous game.
*Bugaboom's boss fight now uses the Cloud Flower and springs, rather than the Bee Mushroom and swinging flowers.
*Coins are now a general collectible like Star Bits, rather than just being collected for a high score. After collecting a Power Star, coins collected are added to the coin collection, similar to Star Bits.
*Checkpoints are now marked by a Checkpoint Flag, rather than being invisible.
*The game now records the time the player has taken to beat the level.
*Luigi is now unlocked after defeating Bowser and unlocking [[World S]], instead of the player playing through the game twice as Mario and Luigi.
*Cutscenes are now done in a storybook format, and the player has to press a button to progress dialogue.
*The game rewards a 1-Up upon collecting 100 Star Bits, rather than every 50.
*Collecting a Life Mushroom while having a full six hit points now rewards a [[Extra life|1-Up]] rather than nothing.
*When receiving a letter from Princess Peach, Mailtoad automatically gives the player 5 1-Ups, rather than asking if they want to accept it.
**Luigi no longer receives 20 1-Ups from Peach's letters, only receiving 5 like Mario.
*The credits are more interactive, with the player playing through various levels in the game, rather than having standard credits.
*The first-person camera is able to turn 360 degrees rather than 90 degrees left and right.

===Levels===
*In the first game, excluding green or red Power Stars, major galaxies had six Power Stars (three missions, two Prankster Comets with one of which being a Purple Comet mission, and a Hidden Star) while minor galaxies had one (the sole mission). In the sequel, these numbers were changed to give major galaxies three Power Stars and minor galaxies two Power Stars.
**The type of stars each galaxy has now varies, rather than having a constant amount of each type per galaxy. Major galaxies have either two missions and a Prankster Comet, two missions and a Hidden Star, or one mission, Prankster Comet, and Hidden Star each. Minor galaxies have either one mission and a Prankster Comet, one mission and a Hidden Star, or two missions (with the second mission being a challenge from either [[The Chimp]] or [[Jibberjay (character)|Jibberjay]]).
*Hungry Lumas that create planets in galaxies now require coins to be fed to them instead of Star Bits. However, Hungry Lumas that make galaxies still require Star Bits.
*Hungry Luma galaxies can be accessed via the World Map, just like the rest of the galaxies in their corresponding world, rather than using an alternate method to access it (a launch star outside of the dome).
*The galaxy icons on the World Map are much more detailed than in the first game, and some of them have more animated features, rather than being completely stationary models. Similar concepts have been used later in ''[[Super Mario 3D Land]]'' and ''[[Super Mario 3D World]]''{{'}}s stage icons.
====Prankster Comets====
*Prankster Comets are no longer categorized by type, simply leaving them as generic Prankster Comets.
*Boss galaxies now have Prankster Comets.
*During Speedy and timed Purple Coin missions, the clock now stops and disappears after the star appears, whereas in the original, the clock continued to run until the star was grabbed.
*Some Speedy Comet missions have clocks that must be grabbed to keep the timer going.
*Cosmic Comets and Fast-Foe Comets do not return, being replaced by Clone Comets and Double Time Comets respectively.
*The game now notifies a player when a Prankster Comet has appeared in a certain galaxy, rather than having to check themselves.
*The player can select any mission in the galaxy they want even if a Prankster Comet is in orbit. Because of this, [[Comet Tico]] and its ability to move Prankster Comets do not return.
*If the player loses a life during a Prankster Comet mission, the game does not ask the player if they want to retry the mission or return to the hub world, instead restarting the mission as normal.

===Music===
*While many soundtracks return from the first game, some returning soundtracks have been remixed to be more orchestrated rather than maintaining synthesized instruments. This includes:
**The theme of [[Bowser's Star Reactor]] and [[Bowser's Dark Matter Plant]], used in [[Bowser's Lava Lair]] and [[Bowser's Gravity Gauntlet]].
**The theme of [[Honeyhive Galaxy]] and [[Gold Leaf Galaxy]] used in [[Honeybloom Galaxy]] and [[Honeyhop Galaxy]].
**The theme of [[Toy Time Galaxy]] used in [[Supermassive Galaxy]].
**The mission selection theme.
**The level introduction theme.
**The [[Power Star]] and [[Grand Star]] fanfares.
**The jingle that plays when the player returns to the hub world.
**The theme of the [[Baron Brrr]] and [[Undergrunt Gunner]] boss battle, used in the [[King Lakitu]] and [[Mandibug Stack]] battles.
*When the star appears, the music changes to the soft "star appears" theme for the rest of the mission, unlike the original, which only played the theme after a boss was beaten.
*When Mailtoad has a letter from Peach, there is no sound that constantly plays when the player is near him.
*During the egg phase of Dino Piranha and Fiery Dino Piranha's boss fights, as well as the first phase of Major Burrow's boss fight, a new soundtrack (namely the theme of [[Boss Blitz Galaxy]]) is used during those sections instead of the originals.
*The Mandibug Stack mini-boss now has an actual theme playing (which shares the same with King Lakitu), rather than using the same theme as the level.

===Aesthetic===
*When Lumalee asks if the player wants to buy a 1-Up Mushroom or Life Mushroom, the dialogue boxes now show their names alongside their icon (like the Japanese version of the first game), rather than just their icon like in the English version of the first game.
*In the American version of the game, when getting an extra life, the text now shows "1UP" like the Japanese version instead of "1-UP" like the English version of the previous game. However, it's still "1-UP" in the European version.
*The "Game Over" text is now yellow instead of pink. The text is also slightly wider than in the previous game.
*The first Star that the player obtains is a Power Star rather than a Grand Star. It is also guarded by a boss, when there was no boss in the first game.
*The text saying "You got a Star/Grand Star" during the star collecting victory animation as well as the text saying "TOO BAD!" during when Mario/Luigi loses a life are slightly larger than in the first game.
*When the player returns to the Starship Mario after obtaining a Grand Star, the text box that appears afterwards says "You got a Grand Star", instead of "You got a Star".
**Similarly, when the player collects a Green Power Star, the text box says, "You got a Green Star", instead of "You got a hidden Star".
*Fiery Dino Piranha's egg now has visible heatwaves around it.

==Development==
[[File:SMG2 Supermassive Prerelease.png|thumb|Mario and two [[Big Goomba|Giant Goomba]]s in an early version of [[Supermassive Galaxy]].]]
The development of ''Super Mario Galaxy 2'' started as soon as the first ''Super Mario Galaxy'' was released. Many of the ideas were based on those shown in the first game, which, for example, included moving or adding new stars in the levels. The project was initially called '' Super Mario Galaxy 1.5''. The development of the new version of the game lasted a year; however, Miyamoto realized that the new game was beginning to overflow with new elements and ideas. Therefore, the team decided to create a real ''Super Mario Galaxy'' sequel rather than a new version of the original installment.<ref>[http://nintendoeverything.com/at-one-point-super-mario-galaxy-2-was-super-mario-galaxy-1-5/ Nintendo Everything >> Blog Archive >> At one point, ''Super Mario Galaxy 2'' was ''Super Mario Galaxy 1.5''] "''As soon as the project was over, we started making something that we might call version 1.5. We did things like moving or adding stars to levels that were already available... we realized that there were too many things to fit into a version 1.5. That made us realize we should start from scratch and make Super Mario Galaxy 2.''" - Miyamoto during Iwata Asks: ''Super Mario Galaxy 2'' interview</ref> The development of the sequel then lasted two and half years.<ref>[http://iwataasks.nintendo.com/interviews/#/wii/supermariogalaxy2/1/3 Iwata Asks: ''Super Mario Galaxy 2'' - Volume 2]</ref>

The game was revealed at E3 2009, along with ''[[New Super Mario Bros. Wii]]''. Although the game was far along in development, it was held back to 2010 due to the release of ''New Super Mario Bros. Wii'' in November 2009.<ref>https://web.archive.org/web/20090612002157/http://wii.ign.com/articles/989/989996p1.html</ref> According to [[Shigeru Miyamoto]], 90% of the features in the game would be new, whereas the remaining 10% were already introduced or featured in the original ''Super Mario Galaxy''. Shigeru Miyamoto noted, "Really what we ended up with is more than 90% of what you'll see in ''Galaxy 2'' is brand new. I'd say closer to 95, maybe even 99%. One of the new things was the inclusion of Yoshi, and also the use of the drill to open up and drill through stages."<ref>[http://www.officialnintendomagazine.co.uk/article.php?id=9227 E3: Miyamoto: ''Galaxy 2'' Is As Big As The Original]</ref> On the other hand, Miyamoto stated in an interview that he wanted to go with as little story as possible for ''Super Mario Galaxy 2''.<ref>[http://www.wired.com/gamelife/2009/06/shigeru-miyamoto-interview/ Shigeru Miyamoto Interview at Wired.com]</ref>

Some of the developers wanted to include characters from other Nintendo franchises, such as ''[[pikipedia:Pikmin series|Pikmin]]'' or ''[[Donkey Kong (franchise)|Donkey Kong]]''. However, Miyamoto shot down the idea. <ref>[http://www.gametrailers.com/side-mission/2012/03/12/super-mario-galaxy-2-could-have-featured-donkey-kong-and-pikmin-cameos-but-miyamoto-said-no/ ''Super Mario Galaxy 2'' Could Have Featured ''Donkey Kong'' and ''Pikmin'' Cameos, But Miyamoto Said "No"]</ref>

CEO of Nintendo America {{wp|Reggie Fils-Aime}} stated that ''Super Mario Galaxy 2'' would be more challenging regarding its predecessor. It was hinted that the new game would implement a tool-assisted guide, similar to the Super Guide from ''New Super Mario Bros Wii''. It was eventually confirmed, although it worked differently. Beginner players could use the Cosmic Guide mode (activated when encountering the Cosmic Spirit) or the Tip Network to learn moves and hints during gameplay. Japanese, European and Australian boxes came with a special DVD to help players to know basic and expert techniques of the game.

==Reception==
Upon its release, ''Super Mario Galaxy 2'' was met with universal acclaim, and is one of the highest rated video games of all time on the aggregation sites Metacritic and GameRankings. ''EDGE'' magazine has given the game a perfect score of 10 out of 10, being the third [[Super Mario (franchise)|''Super Mario'' game]] so far to receive such rating (the others were ''[[Super Mario 64]]'' and ''[[Super Mario Galaxy]]''). ''Official Nintendo Magazine'' grants it a 97%, while ''Game Informer'' has given the game 9.25 out of 10. ''[[Nintendo Power]]'' gave it a 9.5 out of 10. IGN and Gamespot granted the game a perfect 10/10, as well as GamesRadar. Gamespot also gave the game the Best Platforming Award and the Best Wii Game Award of 2010. IGN named it the Best Wii Game of all time. Gametrailers has given a 9.7 from 10, while Famitsu a 37 out of 40. GamePro gave it four and a half stars, X-Play gave it a perfect five out of five stars, and 1UP.com an "A" rating.

|align="left"|"''For all the meaningful changes and additions that have been made, this is still more Super Mario Galaxy--which is to say that it looks and sounds about as good as a game for the Wii ever has, with consistently inventive level design, and exceptionally responsive gameplay. We all like to give Nintendo a hard time for pandering to casual and nostalgic audiences, but when it brings its A-game, it's still able to deliver a fun, accessible game experience that's second to none.''"

|align="left"|"''Super Mario Galaxy 2 is simply an outstanding game. It never rests on its laurels for a second, constantly presenting new objectives and mechanics to push you to never before seen places. Even the two-player mode offers new abilities and delights, making it even more fun to play with a friend by your side. Everything is so well designed and so entertaining that it's easy to get sucked into this world for hours. Super Mario Galaxy 2 is so phenomenal that it's difficult to imagine where Mario could possibly go in the future. But that's hardly your concern now. Mario proves that he is still the king of fun.''"

|align="left"|"''While the [[New Super Mario Bros. (disambiguation)|New Super Mario Bros.]] games have been content to remind us of Mario's roots, Super Mario Galaxy recast him in the role of fearless explorer, leaping into impossible realms, redefining what we could do in virtual space. Here, once again, was the Mario of [[Donkey Kong (video game)|Donkey Kong]], of [[Super Mario Bros.]], of [[Super Mario 64]]. A simple extension of the Galaxy concept, Super Mario Galaxy 2 can't possibly have the same impact. But it does have the same spirit, throwing new ideas at you with gleeful and impulsive abandon, leaving you breathless, scrambling happily to keep up. You can't really complain about more of the same, when the same is the one thing it never is.''"

==Glitches==
{{main|List of Super Mario Galaxy 2 glitches}}
===Infinite Fluttering===
To perform this glitch, [[Mario]] should ride [[Yoshi]] and perform a [[Flutter Jump]]. When he is almost finished, the player should release {{button|wii|A}} and press {{button|wii|Z}}, then, release {{button|wii|Z}} and hold {{button|wii|A}}, repeating this to gain more height.<ref name=SonOfAGlitch>A+Start (Mar 20, 2015)[https://www.youtube.com/watch?v=Ss00G5l2XEc ''Super Mario Galaxy 2'' Glitches - Son Of A Glitch - Episode 40] ''YouTube''. Retrieved March 6, 2017.</ref><ref>Pottoww (Jul 5, 2014) [https://www.youtube.com/watch?v=6vAGSv3bvZI ''Super Mario Galaxy 2'' Glitch - How to Infinite Flutter using Yoshi (Explanation)] ''YouTube''. Retrieved March 6, 2017.</ref> This was discovered by fans very shortly after the game's release. This glitch is known by many fans as "Infinite Fluttering," and has become the most well-known glitch in the game. Using this glitch, players can fight the final boss, [[Bowser]], and also even clear the Perfect Run with [[Yoshi]]. It is also because of this glitch that many other glitches have also been found.

===Red-Blue Panel jump glitch===  
In [[Flip-Swap Galaxy]], [[Mario]] can use the upward momentum from a [[Red-Blue Panel]] flipping up to perform an extremely long, high [[jump]]. Mario must be on one of the non-flipping platforms in the galaxy. Then, he must run toward an empty space that a flipping platform flips to when Mario spins. Right before Mario runs into the empty space, he must spin to make the flipping platform flip to the empty space. Mario should fall onto the flipping platform while it is still rising. Finally, Mario must perform a [[Long Jump]] right before the platform stops moving. The timing for this is difficult, but if performed correctly, Mario does a "superjump" that covers huge distance and can be used as a shortcut.<ref name=SonOfAGlitch/><ref>packattack04082 (Jun 20, 2010) [https://www.youtube.com/watch?v=l1G8YcAgwgU ''Super Mario Galaxy 2'' - Flip-Swap Galaxy - Think Before You Shake - 30.11] ''YouTube''. Retrieved March 6, 2017</ref>

This can also happen if [[Cloud Mario]] jumps immediately after he forms a cloud.<ref name=SonOfAGlitch/>

==Pre-release and unused content==
{{main|List of Super Mario Galaxy 2 pre-release and unused content}}
In the debut trailer from E3 2009 and the two Media Summit Trailers, there were several differences from the game's release.
*The starting planet in [[Boo Moon Galaxy]] was originally going to look similar to the Crystal Planet in [[Space Junk Galaxy]] from the first game.
*When a player used a [[Dash Pepper]], the player did not glow or leave a glowing trail as in the final version.
*[[Good Egg Galaxy]]'s background was used in Tall Trunk's Slide, and in [[Space Storm Galaxy]]'s [[Topman]]'s tower.

*''[[Super Mario Bros.]]'': [[Supermassive Galaxy]]'s music, which is itself a remix of [[Toy Time Galaxy]]'s music from the [[Super Mario Galaxy|first game]], originated from this game's [[Ground Theme (Super Mario Bros.)|overworld theme]]. The first few notes of this music are played when switching between Mario and Luigi. Other music from this game returned from ''Super Mario Galaxy'' as well. In the Grandmaster Galaxy, there is a backdrop featuring elements and enemies, as well as Mario and Luigi in their 8-bit sprites from this game.
*''[[Super Mario Bros. 3]]'': [[Supermassive Galaxy]] is similar to [[Giant Land]] from this game, as the two are of massive size and feature giant versions of common items and enemies.
*''[[Super Mario World]]'': [[Yoshi]], who first appeared in this game, is playable in ''Super Mario Galaxy 2'', and the percussion sounds heard when riding on Yoshi are reused. In fact, when Mario first saves Yoshi, his speech is obviously based on his speech in this game. Additionally, this game's [[Athletic Theme (Super Mario World)|athletic theme]] returns as [[Hightail Falls Galaxy]]'s music (as well as the music that plays during the mission for Starshine Beach Galaxy, "Purple Coin Beach Dash"), and the [[Ghost House]] [[Obake Yashiki BGM|theme]] returns as [[Haunty Halls Galaxy]]'s and [[Boo Moon Galaxy]]'s music. Also, the sound effect that is heard when a [[P Switch]]'s effect is about to run out is used in the bonus areas of ''Super Mario Galaxy 2'', and the sound effect heard when passing through a door in this game is used when opening a door in [[Boo Moon Galaxy]]. In Puzzle Plank Galaxy, the Rainbow Notes play the [[bonus game (Super Mario World)|bonus game]] [[Bonus Men BGM|theme]] from ''Super Mario World''.
*''[[Super Mario 64]]'': "[[Slider]]" from this game is used for [[Tall Trunk Galaxy]] and [[Rolling Coaster Galaxy]]. "[[Koopa's Road]]" theme is arranged once again, appearing in several Bowser-themed galaxies. Also, the [[Throwback Galaxy]] is a replica of [[Whomp's Fortress]]; its boss, the [[Whomp King]], is fought there, and an arrangement of "[[Super Mario 64 Main Theme]]" plays there as well. Both games start with Peach sending a letter to Mario involving [[cake]]. Additionally, the "Inside the Castle Walls" theme can be heard when rescuing Peach and the final Grand Star in ''Super Mario Galaxy 2''. The Rainbow Star theme is an arrangement of "[[Super Star (theme)#Super Mario 64|Powerful Mario]]". Finally, Mario says, "Thank you so much for playing my game!" after the ending credits, just as he did in this game.
*''[[Super Mario Sunshine]]'': The [[Starshine Beach Galaxy]] is based on some elements from this game. The main mission of [[Twisty Trials Galaxy]] is a replica of the secret level found in [[Ricco Harbor#Episode 4: The Secret of Ricco Tower|Episode 4]] of [[Ricco Harbor]]. The red and blue flipping platforms return, although they work differently. A few of Yoshi's sound clips are reused from this game. Piantas also return.
*''[[New Super Mario Bros. Wii]]'': The [[Checkpoint Flag]] returns from this game, and the [[Super Guide#Super Mario Galaxy 2|Cosmic Guide]] and [[Tip Network]] are based on the [[Super Guide Block|Super Guide]] and [[hint movies]] from this game, respectively. Also, the world maps are based on the one from this game. In both games, Bowser is giant, and the final battle is divided in two different parts, the latter having a bigger Bowser. [[Fuzzy|Fuzzies]], the credits cake, and [[Snake Block|pink bricks]] take design elements from Fuzzies, the Koopalings' cake, and [[Ice Snake Block]]s respectively in this game. Additionally, when players collect all the coins in a certain time limit that were accessed by a switch in ''Super Mario Galaxy 2'', the audience claps in the same fashion they did in this game.

[[File:PuzzleSwap SMG2.png|thumb|The ''Super Mario Galaxy 2'' puzzle in the Nintendo 3DS StreetPass Mii Plaza game Puzzle Swap]]
*''[[Donkey Kong Country Returns]]'': The [[Flip-Out Galaxy]]'s concept is back (but slighty changed) for the [[Switcheroo]] level.
*''[[Super Mario 3D Land]]'': [[Star Medal]]s look similar to [[Comet Medal]]s. In addition, the theme used on bonus planets is covered for Mystery Boxes. The blue and red flipping platforms return, but they are activated by jumping. The "beat blocks" return as well. Cosmic Clones return, but they look different. An early theme for the [[Boom Boom]] battle was the same theme played when fighting [[Peewee Piranha]]. Also, a lot of the voice clips, sounds, and enemy animations and behaviors are reused. [[World 7-5 (Super Mario 3D Land)|World 7-5]] is similar to [[Puzzle Plank Galaxy]], and [[Special 5-1]] is similar to [[Flip-Swap Galaxy]]. Also, a strange, ghostly entity can be seen in the woods near the [[Goal Pole]] of [[World 4-4 (Super Mario 3D Land)| World 4-4]], which bears resemblance to the three, strange, black Kodama-esque figures (Hellvalleyskytrees) seen in the background of [[Shiverburn Galaxy]].
*''[[Mario & Sonic at the London 2012 Olympic Games]]'': The Sky Station Galaxy (under the name "Synchro Battle Galaxy") appears in the [[Dream Spacewalk]] event. Puzzle Plank Galaxy's music appears as an arrangement.
*''[[Fortune Street]]'': [[Starship Mario]] makes an appearance as one of the ''Super Mario'' franchise game boards.
*''[[New Super Mario Bros. U]]'': [[Balloon Baby Yoshi]] and [[Glowing Baby Yoshi]]'s abilities resemble to those of Blimp Yoshi and Bulb Yoshi, respectively. Magmaarghs and Magmaws make reappearences as well.
*''[[Super Mario 3D World]]'': [[Green Star]]s make an appearance, replacing [[Star Medal]]s from ''Super Mario 3D Land''. [[Fizzlit]]s return, although in a more square-shaped appearance. The final boss themes (and the Meowser defeated fanfare) have portions of the themes for [[Bowser's Galaxy Generator]]. Also, Grumblumps have a similar appearance to [[Rhomp]]s. The Beat Block mechanic returns under the name "Beep Block", and the Beep Block stages return to the "beep-beep-beep-switch" rhythm as in this game with the same tempo as the [[Beat Block Galaxy]] theme as well. There is additionally a level called [[Boss Blitz]], which is in reference to the [[Boss Blitz Galaxy]].
*''[[Super Smash Bros. for Nintendo 3DS / Wii U]]'': [[Starship Mario]] appears in the background of the Mario Galaxy stage.
*''[[Mario Kart 8]]'' / ''[[Mario Kart 8 Deluxe]]'': The giant dragon used for the [[Dragon Driftway]] racetrack has a similar design to [[Gobblegut]], but with legs. In ''Deluxe'', the battle course [[Dragon Palace]] has two statues of the same Gobblegut-like dragons. In the ''[[Mario Kart 8 Deluxe – Booster Course Pass|Booster Course Pass]]'' DLC, the [[Rock Cup]]'s icon is a [[Rock Mushroom]].
*''[[Mario + Rabbids Kingdom Battle]]'': Gobblegut is used as the base design for a weapon in this game.
*''[[Super Smash Bros. Ultimate]]'': Rock Mario, Lubba, and Starship Mario appear as spirits using their artwork from ''Super Mario Galaxy 2''. Also, Melty Monster Galaxy's theme is added to the ''Super Mario'' franchise track list.
*''[[The Super Mario Bros. Movie]]'': Bowser is shrunken to a small size after his defeat, just like in the end credits of ''Super Mario Galaxy 2''. A [[Dash Pepper]] icon appears on a bottle of hot sauce at [[Punch-Out Pizzeria]] on [[Foreman Spike]]'s table.
*''[[Super Mario Bros. Wonder]]'': The [[Drill Mushroom]] powerup resembles and functions similarly to the Spin Drill item from ''Super Mario Galaxy 2''. Mario's Spike Ball form under the effects of the [[Wonder Flower]] functions similar to Rock Mario.
