You haven't played it, the controls are MORE fun with kinect, not worse, I would rather use kinect with this game than to use a controller because it's fast, precise and MORE fun. This isn't like trying to struggle a play session of halo using shitty kinect controls, this is the real deal and it works beautifully, but someone as close minded as you will never give it the chance.
Of all the reasons people will not buy this game, too short, I didn't like rez, your reason is by far the worst of all because it doesn't even hold merit due to close minded views. I'm a gamer who beat NG2 on all the hardest modes, I play dozens of games a year across all ranges, and I can say that kinect is USUALLY laggy, unresponsive and fickle to a point you have to work with it just for it to function, COE is great because finally something simply works perfectly with the device with little calibration. One of the reasons i'm loving this game is because it finally shows kinect is not only a different way to play, but it can be more fun on a game that uses traditional controls as well. I don't expect this to occur often, but it feels good that it finally did.
