Mario & Sonic at the Olympic Games (series)

The Mario & Sonic at the Olympic Games series is a collection of games that take place during the Summer and Winter Olympic Games, crossing over characters from the Mario series with those from Sega's Sonic the Hedgehog franchise. It debuted in 2007 for the Wii with the Beijing 2008 edition, titled Mario & Sonic at the Olympic Games. Nintendo published the East Asian versions of the first three games and fully published the fourth and fifth games, while Sega published the Western versions of the first three games and fully published the sixth game, with Nintendo licensing characters. The International Olympic Committee (IOC) allowed the licensing deal to lapse in 2020, effectively ending the series.[4][5]
