Kinect works well even if there is little space. It works in the dark and has no difficulty in recognizing players of all sizes, colors, weight, etc. With 1m60 between kinect and the player, it works well, but less than that, a window appears continually asking us to back off. By cons it is impossible to play two with that distance. A minimum 2m otherwise kinect confuses the players. Attention also to the width of the room, he takes as much width as long as many games require that moves horizontally. It's great, especially for kids. I have the Wii but my children 4 and 6 years fail to properly use the levers. With Kinect, they have no problem, it's super intuitive and simple.
