The Wii nunchuck comes with the Wii but you can also buy it seperate. You needs it for certain games. Like boxing or workouts. With workouts you gets both arms moving.
It's a must for certain Wii games. So easy to use and gives you a more authentic feel to the sport you're playing. Helps you get a good workout.
I use this nunchuck every single day on my wii to play sports.
