I got one from Gamestation, think mine got 7 in.
I love it, one player is much the same apart from you can jump (and maybe the it's different as you feel like you are tilting the environment, not the ball).
As for the multiplayer side of thing it is great. There are 50 party games and many are turn based (helpfully every game says whether it requires the nunchuck and if it is turn based or simultaneous)
After that it is a right laugh, disk golf is like throwing a frisbee on a course, you have to get it to the end bit in as least shots as possible, hammer throw requires you to do a circular motion and release it when the time is right). Of course you have all the old favs liek monkey boxing, bowling, target etc, plus new ones like monkey snowboard and fencing.
Bottom line, if you have mates get it!
p.s 12/50 party games require a nunchuck.
