Mario & Sonic at the Olympic Games Tokyo 2020

Mario & Sonic at the Olympic Games Tokyo 2020 is a sports game and the sixth installment in the Mario & Sonic series. It is based on the real-world, which will take place in Tokyo, Japan. This marks the first instance where the series skips an Olympic Games, as Ubisoft bought the rights to develop video games. It was released for the Nintendo Switch in 2019. An arcade version is also set to release in 2020. The game has a companion mobile game releasing in 2020, but only features Sonic the Hedgehog characters. It is also the last game to be developed by AlphaDream following their bankruptcy on October 1, 2019.

Unlike previous games, most characters wear appropriate sports clothing depending on the chosen event. Additionally, the game's title places the location and year after "Olympic Games" rather than before. 2D Events are introduced, which are events from the, only use button controls, and are based off older sports games , utilizing the 8-bit (Mario) and 16-bit (Sonic) styles. The game includes a story mode, which takes place in both 2D and 3D.

Advantages
Excluding the 3DS version of Mario & Sonic at the London 2012 Olympic Games, this is the first Mario & Sonic game not to report the character stats. Instead, the game reports for each character specific advantages that correlate to their character type (All-Around, Power, Speed, Skill) from the first four games. All-Around characters do not have a specific advantage but are listed as "All-Around" in all events. This is the first Mario & Sonic game with character types to have an uneven amount of characters per type, with only five All-Around types, seven Power types, eight Speed types, and twelve Technique types.

Although not reported in-game, each character has advantages even within a specific type. Luigi, for instance, is slower and less powerful than Mario, but has better technical ability.

In the Tokyo 1964 events, all characters have identical abilities.

Playable
Mario & Sonic at the Olympic Games Tokyo 2020 features a total of 32 playable characters, making it the first in the series to feature fewer playable characters than the previous installment. Similar to the Wii U version of the previous game, the 20 playable characters that have been playable since the second installment are playable in all events, while new characters and characters that debuted in the previous game are only playable as a guest in a single event. Guests are unlocked by beating them in Story Mode, though unlike the previous game, not every event contains a guest character. This is also the first home console Mario & Sonic game not to feature Miis as playable characters.

These characters are playable in certain events, but are not selectable and have limited functionalities than other playable characters.

Chapter 1: A Mysterious Game System
Mario and Sonic have arrived at the Olympic Stadium, excited for the Olympic Games. A short while later, Toad arrives, with a gift that is addressed to both Mario and Sonic. They open it to find a retro video game system inside with a letter that reads, "To Mario and Sonic with love, in commemoration of the Olympic Games in Tokyo! We made a little game to let you experience the past Olympic Games in Tokyo. By all means, give it a try!" While Sonic is trying to figure out who sent it, Toad mentions how retro it is due to it saying, "Tokyo '64" on it. Since there's no name of who it is from, Sonic begins to get very suspicious of it. Meanwhile, Bowser and Dr. Eggman are hiding behind the sidelines waiting for Mario and Sonic to turn on the system. After Luigi shows up, Bowser begins to get more impatient and decides to turn it on himself. When he shows up, he scares Luigi, who was holding the system, causing him to drop it and press a button on it. When he picks it back up, the screen begins glowing, which causes Mario, Sonic, Bowser, Dr. Eggman, and Toad to all disappear.

Chapter 2: Dr. Eggman & Bowser's Scheme
In a heavily pixelated world, Mario, Sonic, Bowser, Dr. Eggman, and Toad all fall from the sky into an unknown world. After noticing their 8-bit/16-bit appearances and the environment around them, Dr. Eggman deducts that they were sucked into the video game because whoever the light touches gets swallowed into the game. With Toad's help, Sonic figures out that the system was a gift from Bowser and Dr. Eggman, and that their plan was to get Mario and Sonic stuck in the game. Dr. Eggman created the game while a Magikoopa's magic allowed it to suck them in. However, their plan backfired since Bowser and Dr. Eggman got sucked in as well, with Dr. Eggman claiming there is no way out. Eventually, they realize from a nearby sign that the video game is based off the 1964 Tokyo Olympic Games (hence the name Tokyo '64). Dr. Eggman decides that he and Bowser should compete in the games, much to Bowser's confusion, but he agrees to it so he can win the gold. They head into the stadium with Mario and Sonic following shortly afterwards. They also decide to compete in the Olympic Games, much to Bowser and Dr. Eggman's shock. The event is the 100m, which Sonic manages to beat Dr. Eggman in. After his loss, Dr. Eggman states that he and Bowser will train harder to win the Olympic Games.

Chapter 3: The Search for Tails
Following the disappearance of Mario, Sonic, Bowser, Dr. Eggman, and Toad, a frightened Luigi is left with nothing but the Tokyo '64 in his hands. After telling a nearby Omochao what happened, the Omochao suggests to find Tails, who is great with machines. However, he does not know where Tails actually is. Suddenly, Amy appears to compete in the 100m. She tells Luigi and Omochao that she does know where Tails is, but since her event could not start due to a lack of competitors, she asks Luigi to compete against her in the 100m first. Luigi accepts her challenge and wins against her. After getting beat by Luigi, Amy tells him that Tails went to go watch Karate. She joins Luigi as he goes to Nippon Budokan to find Tails. There, a Red Toad informs them that Tails already watched matches and left, stating he had a promise to keep, but also tells them that he might have gone to the gymnastics venue with Daisy. Luigi goes to the Ariake Gymnastics Centre, where he finds Daisy, who is warming up for the Floor Exercise event. After Luigi asks about Tails, she says they were going to Ariake together, but split up, with Tails going to another venue. Despite wanting to be focused, Amy wants to compete in Gymnastics against Daisy, which she wins. After Daisy’s loss, she asks Luigi why he is looking for Tails in the first place, which also increases Amy’s curiosity since she never asked either. After Luigi explains the situation, Daisy joins Luigi and Amy to find Tails. Luigi decides to go to the Ariake Urban Sports Park, where he finally finds Tails, who decided to compete in Skateboarding alongside Sonic, who is currently absent. After a nearby Omochao announces that the event is about to start, Tails, who is unaware of Sonic’s situation, asks Luigi to take Sonic’s place. Luigi reluctantly agrees and beats Tails in Skateboarding. Afterwards, Amy and Daisy tell Tails of Mario, Sonic, and Toad’s situation and Luigi shows the Tokyo ’64 to him.

Chapter 4: The Secret Trick
In the 1964 Olympic Stadium, the Long Jump event is next, with Dr. Eggman leaving the victory to Bowser, only to lose it to Mario. After his humiliating loss, Dr. Eggman pulls Bowser to the sidelines. After Bowser asks him why they are collecting medals instead of finding ways back to the real world, Dr. Eggman explains to him the only way to get back to the real world is to collect gold medals, with his lie about no way to return being so he does not give any information to Mario or Sonic. However, they are unaware until the last minute that Toad was listening to everything Bowser and Dr. Eggman said, and begins explaining it to Mario and Sonic as well. They go to confront the villains to see if what they said is true, but they managed to sneak out before they could do that. Thankfully, a nearby Pecky tells Toad that Dr. Eggman flew out west, so Sonic decides to chase him while Mario and Toad go find Bowser. While Sonic is trying to find Dr. Eggman, he finds a Pocky who is standing next to his Eggmobile. After the Pocky tells him that Dr. Eggman got on a bullet train, Sonic sees Eggman on the train and chases after it. After Sonic beats the bullet train to Tokyo Station, he goes around and attempts to find Dr. Eggman, who is hiding behind a tree, but to no avail. After he goes somewhere else, the doctor comes out and calls his plan to stall Sonic a success while he uses this time to go find more venues to go to. Meanwhile, Mario and Toad decide to Sumida River to find Bowser. After seeing Bowser flee on a boat, Mario decides to take his own boat and go after Bowser on the lake. After intercepting Bowser’s escapade, they corner him at a dock, but when Toad enrages Bowser and gets behind Mario, they start talking about random things, which Bowser uses as an opportunity to escape. Eventually Sonic shows, up and they both report that their villain got away and they are probably meeting somewhere.

Minigames
There are 10 minigames that are playable in Story Mode. There are five 2020 minigames, where the player plays as Luigi and Tails, and five 2D minigames where the player plays as Mario and Sonic.
 * Tower Climb: Tails must climb Tokyo Tower to reach the Venue Passes at the top. He must grab the holds and use springs to gain height. Falling off or touching the spike balls reduces time.
 * Metropolitan Goal Kick: Luigi has to defeat Metal Sonic by kicking rugby balls into him. He must first steal one from an Egg Pawn, then perform a Try in the center of the arena. He then must release the kick when the meter is full to get the most amount of damage.
 * Kabukiza Clash: A horde of 36 Egg Pawns are standing in front of Kabukiza Theatre. Tails has to shoot them down with an Archery bow and arrow before they throw spiked balls at him. If he gets hit three times, he loses.
 * Shibuya Scramble Search: In a large crowd of Toads and Shy Guys in Shibuya, Luigi has to use binoculars to find four specific Toads, some of which are holding a specific item.
 * Treeside Rumble: Tails must fight 60 Shy Guys, while avoiding the spiked balls they throw. If he gets hit three times, he loses.
 * Tokyo Sky Flight: Mario is flying a plane while Sonic is standing on top of it, and Mario shoot the enemies that he encounters. When he reaches Tokyo Tower, he must take down Dr. Eggman, who fights similar to his appearance in Sonic the Hedgehog. If the plane takes five hits, the player fails the minigame.
 * Bullet Train Blast: Dr. Eggman is sitting inside of a bullet train, and Sonic must race it to its destination. While running, Sonic must avoid spikes, which will slow him down. Along the way, he can collect Monitors which have invincibility and shield power-ups.
 * Sumida River Boat Ride: Mario races Bowser on a boat. While racing, he must avoid Cheep Cheeps and other boats while jumping waves in order to beat him.
 * Highway Chase: Sonic is running on a road and must catch up to Dr. Eggman's taxi before time runs out. While running, he must watch out for other cars and banana peels while stepping on dash panels to speed up. When he reaches the taxi, he has to attack it to inflict damage.
 * Museum Sneak: Mario must sneak through four floors of a museum to reach the top. On each floor he must find a certain amount of keys to open doors. Throughout each floor, various Goombas, Koopa Troopas, Cheep Cheeps, Bloopers, and Hammer Bros. are carrying searchlights, which Mario must not get caught by.

E3 2019

 * The title screen did not have Mario and Sonic on it.
 * The event selection screen used a different arrangement than in the final game.
 * Characters did not vocalize during their award ceremony animations. This was changed in the final game, making it more consistent with previous installments.
 * The music that played when setting a new record was the "London Party is Over" fanfare from Mario & Sonic at the London 2012 Olympic Games, before switching to a new fanfare in the final game.
 * Additionally, the announcer did not say, "New Record" when setting a new record.
 * In 110m Hurdles, the announcer did not say, "On your mark," at the beginning.
 * Oddly, despite being present in the initial reveal trailer, the 110m Hurdles did not feature the placements showing what place characters were in. This was fixed in the final game.
 * No music played during the replay of 110m Hurdles or when characters were shown their results in Surfing. These were both changed in the final game.
 * Peach's 1st place animation had her hold a pose at the end. In the final game, after the pose, she starts waving to the crowd.
 * In Karate, the announcer had three different voice clips: 「始め」 (Hajime), to begin the match; 「待て」 (Mate), after an opponent was knocked down; and 「止め」 (Yame), when the match was over (which matches real-life karate). In the final game, the "Mate" clip (which means to wait) is replaced by "Yame" (meaning to stop) for unknown reasons.
