Mario & Sonic at the Tokyo 2020 Olympic Games

The game received mixed reviews, with praise for the presentation and gameplay, but criticism for a perceived lack of content for single-player, multiplayer features, and the story mode. It is the final game in the series, as the International Olympic Committee chose not to renew Sega and Nintendo's license to produce Olympic video games after 2020, in favor of a new partnership with nWay, who has developed mobile games for the subsequent editions, as well as exploring opportunities in non-fungible tokens and esports.

The game features a variety of events; returning ones from previous Mario & Sonic titles include boxing, soccer (referred to as football in the game), swimming, and gymnastics, while new ones include karate, skateboarding, sport climbing, and surfing. The game supports a variety of controllers, including the Joy-Con motion controllers. The game also features single system split-screen multiplayer, LAN multiplayer, and online play. An additional 2D Mode is also included, based on the 1964 Summer Olympics, and featuring 8-bit and 16-bit styles for Mario and Sonic, respectively. These 2D Mode events have more limited controls and the option to enable a CRT overlay to further emulate the feel of games of that era. There are thirty-two playable characters in the game. Similar to the Wii U version of the previous game, the series' regulars since the second game are playable in all events while the other twelve are only playable in one event as a guest. Guest characters include Larry Koopa, Wendy O. Koopa, Ludwig von Koopa, Diddy Kong, Rosalina, Toadette (who is the game's sole newcomer), Dr. Eggman Nega, Jet the Hawk, Rouge the Bat, Zavok, Zazz, and Espio the Chameleon. In order to unlock these guest characters, players have to progress through the game's story mode.
