I ran to a store and bought an xbox console + kinect bundle and Dance Central this morning. I've used it for more exercise minutes (and burnt more calories) in one day with Dance Central compared to Wii Fit for two years.
Dance Central is a great way to workout if you love to dance. The workout mode asks for your weight and judges your calories burned by how much you're moving.
The dance battles are a fun way to practice a song with a friend – and the only way to leap into harder difficulties before unlocking them in single play.
I really like the way you choose a song and then choose what mode you play it in. You can easily play in different ways without any hassle. For example, you could start with a dance battle, then perform solo, then break it down to learn moves – all without having to quit out to a menu.
Dance Central is obviously well designed. I'm just hoping for more pop and disco songs to be released for download, as the track list is quite hip-hop intensive.
