It has everything that the original was missing plus more. It has new modes, better visuals, and a download store. I also think the songs are choreography are much better in Just Dance 2.
My favorite new mode is the Dance Battle. Up to eight players split off into two teams of four and then compete in a series of dance minigames. It is so much fun to battle hubby.
If you get tired of the songs or want to add new one you can purchase them for 300 points from the Wii shopping channel.
Overall I think Just Dance 2 is a great game and I would Highly recommend it.
With Christmas almost here Just dance 2 would make a great stocking stuffer.
Just Dance 2 can be found online at Amazon or in stores at many major retailers such a Walmart, target, Best Buy etc.
