Bought it last night and only had the chance to dance about 3 songs but it looks really good! So far not much of a song selection but I think there must be more to unlock. Was going to play today but not enough time but I'm gonna get into it this weekend!!! I think its worth the 70 bucks cause the game is great and you get 2 dance pads!! I already have 1 dance pad cause I play Hottest Party 1 and 2 on Wii, but I'm holding onto the other 2 I just got since the dance pads tend to wear out over time.
My only thing against it is I can tell I'm going to beat the game really quick, I'm used to DDR, I play it on Wii and PS2, and so far the dances on Disney grooves is seeming VERY easy, so for a lot of people that will be a good thing but I was just hoping it would be about the same level of difficulty as my other DDR games.
