Rayman Raving Rabbids (Wii)
This is a fun game, theres no attempt to be the graphically most impressive game with a fantastic AI, this game is all about what the Wii does best, making fun games which are simple to use and fun to play. There are some parts which appear to have issues with either controller accuracy (in one game you have to hit some radios, but it seems to not always work), but the shooting section has had my wife comming back time after time for another go and she's not a fan of computer games in general (although a game where you shoot cartoon rabbits with sink plungers is, apparently, something she's not tried before).
If you're looking for a game thats easy to get into that you can dip into for 5 or 10 minutes play now and again then this will hit the spot.
