Mario & Sonic at the Olympic Winter Games (Wii)

Mario & Sonic at the Olympic Winter Games is a sports game for the Wii and Nintendo DS, and is the follow-up to Mario & Sonic at the Olympic Games. The game is produced under license from the International Olympic Committee in relation to the Olympic Winter Games taking place at Vancouver in 2010. Like the previous installment, this game is a collaboration between Sega and Nintendo featuring characters from both the Mario series and the Sonic the Hedgehog series.

Although Sega was handling most of the development for both versions of this game, as it did for the original Mario & Sonic at the Olympic Games, they were also handling publishing/marketing duties for all territories outside of Japan, while Nintendo has done publishing/marketing duties for Japan itself.

Versions
The game features modes that are exclusive on the Wii and DS versions.

Wii Version
The Wii version employs the Wii Remote controls, as well as the Wii Balance Board. The game features a Festival mode where the player starts from the opening to the closing ceremony. In the Festival mode, the player can choose to play an individual festival, where the player faces off against 7 other CPU characters, or a team festival, where the player can choose three other teammates to play.

New to the game is a marketplace that allows the player to purchase various items such as clothes and accessories for the player's Mii, tunes from both series, and customizable snowboards. Players can purchase these items using Star Tokens, which he/she earns based on his/her performance. Also, the gallery for Olympic trivia has now been replaced with the Library.

Also, all authentic (real-life based events) are unlocked from the start. Dream Events are in this game and all of them (excluding 2) need to be unlocked.

Trivia

 * Most of the DS profile artwork is borrowed from earlier games like Super Mario Galaxy, Super Mario 64 DS, Mario Party 7, Mario Party DS, Dance Dance Revolution: Mario Mix, Mario Party 8, Sonic the Hedgehog (2006), Mario & Sonic at the Olympic Games, and Sonic Unleashed. Other art is either new or borrowed from the Sonic Channel. For the female participants in this game, the difference in their profile arts is that they are wearing their respective winter outfits.
 * Bowser's profile artwork is the same as his artwork for New Super Mario Bros. Wii, which came almost a month after this game.
 * An app based on this game was released for Apple's iPhone and iPod Touch, but only features Sonic characters and thus is named simply Sonic at the Olympic Winter Games. This game has since been removed from the AppStore.
 * This is currently only game in the series to be released on both consoles on the same day.
