Mario & Sonic (series)

The Mario & Sonic series is a collection of crossover sports games featuring characters from Nintendo's Super Mario series and Sega's Sonic the Hedgehog series. This series marked the first time Mario and Sonic ever appeared together in a video game.

The series began when Sega acquired the license to create videogames based on the Olympic Games, intending to create a version featuring characters from its well-known Sonic the Hedgehog franchise. Due to the atmosphere of competitive sportsmanship the Olympics had to offer, Sega received approval by Nintendo to include Super Mario characters in the game with those of the Sonic series. The series has been overall well-received by the media, mainly for being a crossover between Mario and Sonic, with the gameplay and multiplayer having been praised as well. However, it has been criticized for the choice of setting for both series, the controls, and having the Olympics be the only theme in the series.

Mobile phone tie-ins
Following the release of Mario & Sonic at the Olympic Games, Sega published Sonic at the Olympic Games, a -based mobile phone game that features characters from the Sonic the Hedgehog franchise competing in the 2008 Beijing Olympics. Despite the similar premise, no Mario characters or references appear in the game.

Sega would publish another mobile title shortly after the release of Mario & Sonic at the Olympic Winter Games, called Sonic at the Olympic Winter Games, this time on. It similarly featured Sonic the Hedgehog elements but no Mario elements appearing at the 2010 Winter Olympics. It was taken down from the App Store a short time after release, with no reason currently given.

Another game called Sonic at the Olympic Games, this time set during the 2020 Tokyo Olympics, is set to be released worldwide for iOS and platforms in spring 2020.

Trivia

 * As the announcement of the Mario & Sonic Olympics video game series was revealed (starting with Mario & Sonic at the Olympic Games), the agreement was also reached that in the case of publishing and marketing duties for each Mario & Sonic Olympics installment, Sega would handle the process for all territories outside of Japan while Nintendo would handle the process inside of Japan itself. The fourth game, however, was published by Nintendo outside of Japan rather than Sega. Nintendo has since published subsequent titles globally as well.
 * The Pyeongchang is the first and currently only time that the Mario & Sonic series did not have a game to coincide with the event since the start of the series. This is due to Ubisoft having the rights from making PyeongChang 2018 Olympic Games video games.
 * If the handheld versions are counted separately, 100m, 100m Freestyle Swimming, and Javelin Throw are the only events to appear in every Summer Olympics installment in the series.
 * Bowser and Dry Bowser are the only Mario characters to change their voice actor during the series (switching from Scott Burns to Kenny James in the third installment). Conversely, Dr. Eggman and Eggman Nega are the only Sonic characters to keep their voice actor in every installment (keeping Mike Pollock as their voice actor).
