Seem a bit rush game lack a bit content but capture the key element.
The game has very nice menu kinda remind of of kung fu from ps3 game. Capture the player live movement and not using avatar or other artificial character.
Just aware you need a lot more rooms to work than dance central, the soundtrack is not complete, problem is some songs only dance and some only sing, the popular track does both. Definite not worth $50, buy it for $40 is probably a keeper for that price. Wish they had update and improve the game content.
The game does has nice video tutorial of all songs from real dancer. Since I do play dance central, DC has better set of different songs and difficulty. DC definite has more in dept in term of pure dance moves. However DC doesn't has sining or capture live of the person but do a lot of replay video.
If you like DC you should check out this one a bit different. Since Kinect lack many good game, this is decent and good choice for those who like DC.
