Mario & Sonic at the Olympic Games is a sports game that places Mario, Sonic, and their various allies against each other in Olympic events. The game has the official Beijing 2008 Olympics license, and features environments based on actual Olympic venues.
Originally, Mario & Sonic at the Olympic Games was considered an April Fools Joke as the game was revealed late March. However, soon after, Sega stated on their official website that the game is official, and that both Sega and Nintendo are working on this game project. Shigeru Miyamoto then soon confirmed that he would be supervising the project, confirming Mario & Sonic at the Olympic Games to be real.
Mario & Sonic at the Olympic Games is available for both the Wii and Nintendo DS. Both versions of the game utilize the new functions of these consoles completely. Mario & Sonic is compatible with Nintendo Wi-Fi Connection.
