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 make video games. It was released for the Nintendo Switch on November 1, 2019 in Asia, November 5, 2019 in North America, and November 8, 2019 in Europe and Oceania. 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.

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.
