First of all this only works with games designed for it. So it won't change the control of any old game. So far only three games use motion plus, Virtua tennis, Grand slam tennis and Tiger Woods. Forget virtua tennis, motion plus was a last minute addition, Grand slam tennis controls brilliantly, you swing the controller in the same way you would a tennis raquet allowing you to precisely place your shot and add topspin or slice, and it works very well, occasional errors are due to the player not making the correct motion. Tiger woods also has a superb control system though it probably is'nt as significant to the game as tennis. In short, if you are interest in the games i mention get motion plus, end of story.
