If there was unlimited time, I would create a game for it
Along with id Software’s John Carmark, Cliff Blezinski has expressed his desire to create a game that uses Kinect; but time is not unlimited and there isn’t a team available to do it. It is something that he would love to do, but just can’t make it happen right now.
As for the possibility of Kinect in the next Gears of War game… Cliffy B suggests that it is something that they might explore, but only if they could do it right. Still, hearing that Kinect support is possible for the next Gears of War makes things a bit interesting.
