Actually, for Mario Kart Wii, you don't have to have the steering wheel. It works exactly the same without the wheel, you just turn the controller sideways. Silent Hill: Shattered Memories looks like it will be a really good game, although it's not set to be released until October, I believe. Animal Crossing is a good game, too. Boom Blox is more of a party game but I've heard that it's a good one, although I haven't gotten the chance to play it myself. Most Mario games are good. There's also going to be a new Super Mario Bros coming out for the Wii that will be a multi-player game. The Conduit, Red Steel and No More Heroes are more action-type games that are good, but definitely have to be the type of games you're used to playing.
Also, one last one. Dead Rising is a SPECTACULAR game. I really do love that one.

I hope that helped.
