I'll +1 the quality of the workout with Supernatural. I was a heavy XBox fitness user and loved the workouts available, along with the use of the Kinect to gameify and make sure I wasn't cheating. Supernatural offers the same thing to me. Workouts are intense, hard, and fun somehow. It took a little work to make sure I was timing things right and making the right motion for my moves to count, but the result is fun. To make it even better, I connect bluetooth audio to my home theater AVR and enjoy a much better music experience to get pumped up.
