My son and I have noticed that about 1/3 of the mini-games don't appear to work, to put it bluntly. The wii-mote movement is either not moving, or not showing up, or bouncing all over the place. I think there was one game where we found the instructions were not correct, but can't remember which one. Anyway, has anyone else noticed alot of these games not working? We're thinking about taking the game back for exchange. Thanks!
