Either Super Mario Galaxy or New Super Mario bros wii.
Mario Galaxy has more levels, more of a variety of levels, more creativety and imagination, is longer, has a massive "cool" factor (levels, secret levels, powerups, enemies) but has a terrible 2-player mode, small storyline, complex controls and becomes boring rather quickly.
NSMBW has a great 4-player mode, has a wide variety of bosses, has simple controls and is more original but has less levels, less variety of levels and a more "been-there-done-that" factor from the ds version and throughout the game.
I personally think that Mario galaxy is better because of the creativity and range of levels.
Wii sports is. Before that it was Super Mario Bros.
Probably one of the Super Mario Galaxy games or a Call of Duty.
Mario Kart Wii
The Mario Kart video game for the Nintendo Wii, along with the Wii Wheel accessory, can be purchased in a variety of places. Wal-Mart, Target, Best Buy, and Gamestop, for example, all sell these items.
The most recent Mario game on the Wii is Mario Kart. Nintendo recently announced that New Super Mario Bros. will be released during the 2009 holiday season.
Mario Kart Wii is da best!
It used to be Super Mario Bros. for the NES (Nintendo Entertainment System) and it used to be the most bestselling game in the world, but now it is Wii Sports, which is now the most purchased video game in the world.

By far the best two to four player racing game on the Wii is Mario Kart. It's fun and fast and offers a wide variety of cars, tracks and characters to play.
Kevin Jonas` favourite video game is Mario Kart Wii
Mario Carts is a pretty popular game for the Wii. However, I think the Super Mario Bros, that is due to come out in November 09', will be much more popular.
