Wonderful game! The truth is, I don't know if it's a game as much as it is exercise or dance lessons. It came to us as a gift, and when I saw my son (5.5 years old) having fun dancing, I couldn't resist and I've been dancing to Michael Jackson's rhythms ever since. All the songs are well-known, so the players (up to 4) know what to expect. The choreographies are simple, but with the King of Pop's signature moves, and it's a very entertaining way to do cardio and muscle toning! Although in some songs we have the option to choose easy, normal, or hard (unhuman for Thriller), or to follow MJ's moves or one of the backdancers, the choreographies are much simpler than those in the videos, so I give it one star for lack of progress. The game also offers dance lessons with specific moves from songs (which you can unlock as you progress in the game) performed by dancers.
