Your favourite Kinect game?

[T-Rok]

My uncle recently bought Kinect and I must say its amazing. I can't stop playing.. well as long as my body doesn't quit I can't. I've played a few games, but I must say my favourite game is Dance Central. It is amazingly fun. It was created by the same people who do Rockband and they did a great job.

But what I want to know is whats your favourite game for Kinect? If you don't own Kinect, what is your opinion on it and why don't you own it?
