What are your favorite Family playable Games?

My wife was never much of a gamer, but I got her a Wii as a gift figuring it would be different enough to maybe catch her interest. It has, and since we are running out of games to play I have been looking for a good list of co-op type games that are more family friendly. Any suggestions?
