the Kinect is part of the system here. all retail Xbox Ones come with it so developers assume you have it. half the time my Kinect is pointed at the wall but i do always have it plugged in for voice commands.
with the Xbox 360 Kinect was optional and more people didn't have it than had it. honestly i'd rather buy a PS4 if i didn't want the Kinect and get the full system. on the PS4 the camera is always optional. what does one do when a game comes out that you need Kinect on because like i said its part of the system and all the retail systems come with it?
