ummmm, sorta this is like Natal. The difference is that the webcam oh sorry PS EYE is calculating based on 2d images. Where as Natal uses 2 cameras to match a 3d position of the user to one stored in it's database. So games like this can't judge depth and the game proves exactly that. It's all 2d motion.
Though Personally I love games like this :)
Squilliam: On Vgcharts its a commonly accepted practice to twist the bounds of plausibility in order to support your argument or agenda so I think its pretty cool that this gives me the precedent to say whatever I damn well please.
