finally found a wii this weekend for my 9 year old sons birthday next month i have been reading about the poor battery life of the controllers my questions are: is there a corded wiimote nunchuck controller available? do you have to use the nunchuck controller for all games? can you use a traditional Nintendo controller for all games? what else does he need to enjoy the system with a few friends other than a few games? do i need to by another nunchuck and traditional controllers?
