Looking for a simple multiplayer 360 game?

I'm looking for a simple xbox 360 multiplayer game I can play with my mom. We've tried Fusion Frenzy and it's too complicated for her (game play is too fast, details too dark for her to see easily). It doesn't have to be a four player game, two player is fine. We've played together and enjoyed Spyro (Wii) and Mario Party (Wii and N64), so we're looking for something along those lines of complexity. It's okay if the game is a bit childish or a little too easy. Any suggestions?
