Wii, as everyone else said. Motion and the games were fun. I wish to play them again... 
What happened to your Wii?
Nothing. Earlier, I had the discs put in backwards. That was why I couldn't play the Wii. A silly mistake, I know.
Anyway, some games were easy or challenging, but for the Mario games, they have been easy ever since Wii was manufactured. Nintendo should add a little more difficulty to Mario Wii Games in the future, IMO.
