This review only has one review through Best Buy, but a bunch through Amazon and they are all really good. Here is one of them:
As an owner of the original Kinect game, and a player of many other workout games since (UFC, Biggest Loser, etc) I have to say that I’m pleasantly surprised with this new version.
As the original one did, the game gives you a body scan when you originally sign in. That image is then what is used to play games. Oddly enough though, I’ve yet to find anywhere in the game where I can modify anything it measured. It also didn’t ask me for my weight so I have no idea where to input that or update it. It did recognize that I was a previous player and carried over my calorie burn count which I thought was great. After that, a ton of achievements were unlocked, which I also didn’t mind 🙂
