Summary: Fun once you get used to it. It's very similar to Samba de Amigo from Sega. The single player mode isn't that great(its pretty much just practice for the multiplayer mode) but the multiplayer mode is. The object of the game is to touch the moving smiley faces.
Summary: When I first bought Eyetoy: Groove the game was very hard to get used to after playing Eyetoy: Play. If you are thinking this is like DDR (dance dance reveloution) it's not because you are not always looking at your feet. The songs on groove are one minute longer than the songs on DDR.
Summary: EyeToy Groove is a follow up to the higly sucessful Eyetoy Play. Instead of hitting ninjas or cleaning windows you wave, swipe, hit and pose. It also has a calorie counter that will tell you about how many you have burnt while dancing.
