Mario Kart Wii
Super Paper Mario
Wario Ware
Boom Blox
Rock Band (Soon enough)
Don't bother:
Sonic and the Secret Rings (The controls barely work at all and the Must do (x) number of mission that aren't clear are a fail in any Sonic game look at Sonic 06')
I personally am too picky with games, as FPS's don't appeal to me, and paltformers are rare, so it's hard for me to find a good Wii game to enjoy that is single player. Multiplayer though is another business. Wii Play's Duck Hunt, Wii sports Baseball/Bowling, Brawl and Mario Kart with friends and/or online is what makes me liket he Wii. If I liked FPS's I'm sure I'd love the Xbox360 but I don't .
