Ever since we bought Just Dance 2 for the wii we have been playing it non-stop. The kids and I LOVE it and I get to squeeze in a bit of exercise too. If you really work-it, you will totally break a sweat and burn some calories. The kids favorite song is Monster Mash:
Utley wants to know what all the fuss is about...
And Aiden couldn't help but do a victory cheer when he stole the crown from me and beat me! I may or may not have let him win (ok...I didn't...he won fair and square).
If you have a wii you should really get this game. It is a ton of fun!
