Dance games, at their best, can be perfect examples of videogames at their purest and most universal. Like Pac-Man, like Space Invaders, like Guitar Hero, you don't need to know anything at all about games to enjoy Just Dance. All you really need to understand is the title. You don't even need to be a good dancer � what matters isn't whether you've got killer moves, but whether you actually like to dance. If you don't (what is wrong with you?), then Just Dance 3 can do very little to change your mind. But if you do, this is fantastically entertaining.
