I really wanted this game to be good. Sadly, Dance Central and ANY singing game are better in everyway.
SINGING (the wost part): You can sing whatever note you want as long as you nail the rhythm... Take my word on this. I live making music. There´s no melodic line at all. Michael Jackson was a great singer and this game doesn´t do him any justice.
DANCING: You have all those great dance steps to do and just by moving a stiff leg and lifting your arms you get a praise. And the saddest thing is that it doesn´t have a step by step learning tutorial like Dance Central has. You just get some videos of some great great dancers showing you how to do it, but it´s too fast and the kinect doesn´t control you at all. It´s just a waste. It could have been a great opportunity to actually learn some of those amazing dance moves.
PROS: Nice graphics, great songs and probably a lot of fun to watch your friends grabbing their crotch.
