Mario & Sonic at the Olympic Games (Wii)

Mario & Sonic at the Olympic Games is a sports game for the Wii with a Nintendo DS version of the game released as well. The game 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.

Although both Nintendo and Sega worked on this collaboration, most of the development was handled by Sega. However, as the game was completed, Sega did publishing and marketing duties for all versions outside of Japan, South Korea, and Taiwan. Nintendo did publishing and marketing duties for the Japanese, Korean, and Taiwanese versions of this game.

Both versions of the game use the new functions of these consoles completely. The game was compatible with Nintendo Wi-Fi Connection.

Originally, Mario & Sonic at the Olympic Games was considered an April Fools' joke, as the game was revealed on March 28, 2007. 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.

Playable characters
The game features seventeen playable characters; eight from the Mario series, eight from the Sonic series, as well as Miis. These characters are broken up into four groups; All-Around, which consists of characters who neither excel or descend in any type of abilities, Speed, which consists of characters who are best at agility and stamina based events, Skill, which consists of characters who are above average skill and stamina, but have low power and top speeds, and Power, which consists of characters who are best at strength and endurance based events. In Dream Fencing and Dream Table Tennis, players can use special attacks, which are powerful moves that inflict more damage or knock the opponent out of the ring (Dream Fencing), or hit the ball with more power (Dream Table Tennis).

Trivia

 * This is not the first time that Mario takes part in the Olympics. He also competed in an event called "Intergalactical Olympics" in the Club Nintendo comic "Super Mario: Verloren in der Zeit".
 * The DVD set of The Adventures of Super Mario Bros. 3 was re-released in a double pack with The Adventures of Sonic the Hedgehog Volume 1 to tie in with the release of this game.
 * A version of this game was also released on mobile phones in June 2008, but lacked Mario characters and only included Sonic characters. Because of this it was simply titled Sonic at the Olympic Games.
 * Princess Peach and Princess Daisy were originally going to have swimsuits for the aquatic events. However, this idea was rejected by Nintendo. Eventually, Peach, Daisy, Amy, and Blaze were given swimsuits in Mario & Sonic at the London 2012 Olympic Games.
