I would like to say the same thing about "Let's Tap". That game is selling like hot cakes at my local Best Buy's and its a casual game just like Just Dance.
It's just Let's Tap has five games and they all involve you tapping on a flat surface with the Wii-mote near. And Just Dance reminds me of Let's Tap because with Just Dance all your doing is holding the Wii-mote and dancing and the Wii picks up on your gestures.
Not bad games but it certainly caters to the casual audience. Check Youtube and search "Just Dance" and watch all the results, you will see so many videos that were uploaded from users
