Since the concept of the Wii, everyone knows the principle of "move". Instead of holding the handle (not always convenient for some movement in my opinion), you hold a dedicated accessory to the game and you do the real movement (or almost). The camera (the present) analyzes the movement of the knob "move" (to buy more) and displays it on the screen. Obviously we win immersion and fun of the game!
By cons, be careful: all games are not compatible with the move function !!!!! And also plan on purchasing the directional joystick more (I do not see how we could effectively hold a PS3 controller in one hand and move in the other), which weigh down even the final bill ...
