Any Rockband game (easy mode is really easy to pick up and you can always play harder modes).Sonic All-Star Racing Transformed (fun cart game, I had more fun with it than the last Mario Kart).Any beat-em-up remake on PS3 or XBox Live (TMNT Turtles in Time, etc).As a wife who co-ops with her husband, I'll throw out some easier games (not difficulty wise, but controls wise) that we have tackled together.
