Well, it definitely depends on your preference of games. The wii has a wide variety of games that are challenging as well as fun using the innovative wiimotes. if your looking for adventure games, The Legend of Zelda: Twilight Princess is most definitely the best right now. Although the new Metroid Prime game coming out looks fantastic too. For a Party game, Wii Sports is a great introduction to new wii players (and it's free w/ the wii), but Mario Party 8 is also very fun. Warioware is also a good fast-paced game that has good interaction w/ the wiimote. But like I said, it all depends on what genre you want to play with.

I would have t say legend of zelda...you can play that game for a long time (by the way i noe the iphone has nothing to do with it, but i accidently added the image and dont know how to remove it)

Mario Strikers is currently my favorite game. Especially when playing with friends. The Striker Cup is a bit tedious and challenging but this is a great game overall. Playing 2 v 2 online is a blast too.

I second Mario Striker. It's great game to play alone or with friends.

Rayman raving rabbids!!!!!

Mario strikersssssss!
