Wii games

Well we kinda got the Wii so that my wife will play it with me and so that we can play it with friends when they come over. So we want relatively easy to pick up games that we can play just the two of us or that we can play with 4 people. We really like the Wii sports and I was thinking of getting Wii play also. I also heard that there is a Cranium trivia/board game for the Wii that would be good too. My wife hates the xbox because she can’t play it and isn’t good at any of the games. All I have for the 360 are sports/shooting/racing so they aren’t really her cup of tea. I know she wants mario kart because we used to play that on nintendo 64.
