Sometimes I think about the parallel universe where Sony went ahead with their plan to include their motion camera system with the PS4, which would have complemented Xbox’s Kinect.
It would be interesting to see how many games include some kind of camera/motion feature today…
One of the things I remember very keenly from the Xbox 360 Kinect was that in Forza Motorsport 4, you can turn your head to move the camera in the driver view. This was such a good feature because it meant that I could check my mirrors naturally without worry.
