Mario & Sonic at the Olympic Games (Nintendo DS)

Mario & Sonic at the Olympic Games is a sports game for the Nintendo DS with a Wii 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.

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.

Both versions of the game utilize the new functions of these consoles completely. Mario & Sonic is compatible with Nintendo Wi-Fi Connection.

Playable characters
The game features sixteen playable characters; eight from the Mario series and eight from the Sonic series. These sixteen characters are broken up into four groups of four characters. 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. 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

 * Although both Nintendo and Sega worked on this collaboration, most of the development was handled by Sega. However, as the game was finalized, Sega did publishing and marketing duties for all versions outside of Japan (United States, Europe, Australia, etc.). Nintendo did publishing and marketing duties for the Japanese version of this game.
 * 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 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.
