Undeniable contribution in terms of gameplay, it does take a dimension that claimed the Wii since its release. Wii Sports Resort is definitely more fun to play a wii classic sports (although we regret that the pro level does not bring more bonuses than that ...): the movements are more fluid, more natural. Golf is really better as much more sensitive (no more tantrums during putts) and the Frisbee is really a good idea.
There are however likely that Nintendo will release the Wii Remotes with an improved accelerometer (motion plus function) once this accessory will be sold well and standardized!
A little regret, and as a warning to those who, like me, have wireless nunchuks (unofficial accessory so) it is impossible except by damaging his nunchuk motion plus connect to!
