Even though I am not a fan of Microsoft's Xbox I think it would be cool if the Kinect could recognize a child and prevent the child from playing M rated games online, then the Kinect would ask for the parents approval via face recognition.
It won't sell well because its not a multiplat game. Should've went multiplat instead getting bribed by M$ for timed exclusivity, and now the PS4 would have to wait a full year, or more, for the game to get released on PS4. Once it goes multiplat it will most likely sell more than cod.
