Mario & Sonic (series)

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

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 franchise. Due to the atmosphere of competitive sportsmanship the Olympics had to offer, Sega received approval by Nintendo to include Mario's characters in the game with Sonic. The series has been overall well-received praised 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.

Trivia

 * The first game was believed to be an April Fools Joke as the game was revealed on March 28. However, soon after, Sega stated on their official website that the game was official, and that both Sega and Nintendo were working on the game project.
 * Additionally, 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.
