I love dancing and this product really tests you be it as a novice or pro dancer you'll find something to challenge you and this game is a real party starter, we've had several parties since buying this and everyone loves this game especially after a drink or two.
The graphics are superb love dancing with Emelia or Taye and wait till you unlock Elliot is all i'll say.
For the songs with well known dances these are incorporated normally at higher levels otherwise you feel like your actually learning a routine.
The workout option is good for estimating how many calories you burn whilst having a barrel of fun and if you get good enough the is an option to dance without the flashcards which is really good at testing your skills at remembering the dance.
You can buy new tracks from xbox live and currently we have Disturbia (good dance), Temperature (Top Notch), Word Up (love the Tug of War) and Because of you (think the calibration could be better as it struggles to match the smaller moves)
All in all the best game i've ever played, without a doubt 110% better then Just Dance as the whole of your body is monitored.
