the nunchuck is only for playing normal games they say...
if you are playing ping-pong or other party games you need just a second conntroler...
or mulit games with one controlers were you use the same like some wii games...
or some games need 2 controllers....
i think you need a starter kit(controler/camera/game)+controler
if you have a camera (2controlers)
the kit can be 70/80(less than 100,amazon sells the eye 30+controller price)
and a controler 40/50
but many ppl that i know have a ps3/360 AND a wii fro playing motion games for fun...
wii is the monopoly on this untill move/natal.
i was temped to get a wii to play some party games for fun lets say,now i can get the move or natal whan its out as an adition to my console and thats cheaper...
so if you need a console for gaming and just the wii for some party games ypu can get this/natal instead a new console IF you were planning to spent money on the wii only fro the motion controlls....i think they are is a market for move/natal they know that and BOTH companies will try to make it look as a new platform,meaning you get something new like a wii,not an accessory.
