Wii MotionPlus - including so I could imagine me nothing. As an add-on to the UK import free while we have it since this morning in use. And I must say, it does definitely noticeable. The 10 new games I can do no comparison - the Golf and bowling but I note that you have to dominate the Controller better. Movements are transmitted much more precise, will give balls / ball a drive now to practice and no longer a matter of luck. Can not recommend it more! HAVE FUN
