By comparison against I find this new much more powerful and challenging game than the first. It is very punchy, much faster and physically. There are more songs (plus one can download).
The pros:
_45 Songs in all styles, the newest and my childhood, even my parents lol (really for everyone)
_excellent for sports and sweat profusely
_of fun options to play with friends or even alone
_a better motion recognition (by cons must be damn rhythm)
_l'apparence is very disco, personally I like.
The -:
_mon son can not play, the choreographies are too harsh for him in terms of coordination and speed
Basically I recommend it 100% because that's what this console are: using his whole body to play and there between the legs, ankles, chest, arms and coordination hand / eye / leg ... everything moves in the muscles and in the brain ...
I only take games that move, that's why it is done and this one lives up to its promises ... to when the game via the Internet to compete with big names?
Oh yes, and I integrate into my fitness program, it's very appropriate
