You find moving your feet to move complex? You find looking around or moving your hand to move a camera complex? You find pointing to aim and moving your fingers/thumb/hand in someway to shoot complex? How do you function in life and how the hell did you work out how to use a keyboard? Lol! And of course the Kinect is capable of all that and I wouldn't be surprised if some if not all of those things are featured in launch games. (One of the sports games has paintball which could use controls like that.)
Do you really think that its a practical replacement for a controller? If so more power to you, you're gonna need it when you dance all over your living room playing some basic shooter.
Who said it's a replacement for joypads? As far as I know if you buy a Kinect Microsoft won't come and confiscate all your other controllers, lol! It's a new controller experience that I hope developers will take full advantage of in the future. There will be games that you clearly couldn't imagine and probably some that I couldn't imagine either. I've got some great ideas including at least 2 ideas for things that aren't really games, but I'm not going to post them here! (Or anywhere else for that matter, at least not anytime soon.)
Its a limited experience. Which is what we are discussing.
