Tried Kinect 2 days ago. My friend works for a game dev and got a set for free about a week ago.
I have to say, quoting my friend "it is a FREAKING PS EYE!!!" I still remember playing silly games in the PS2 era. That's exactly how you feel with Kinect.
I am still more incline to a controller based gaming experience. It gives you that fine touch that you can learn how to play better, with Kinect, you are just waving your body like a monkey.
