The remote control is required for a handful of games on the Wii, they support the so-called Wii MotionPlus. The most prominent example is probably Zelda Skyward Sword, which runs only with this Remote Plus. More titles are Red Steel 2, Wii Play Motion, Wii Sports Resort. Then there are some other games the Wii MotionPlus support but not necessarily presuppose. Hardware makes no problems, can sometimes fall down and remains unbeschadet.Batterien are included. Find the black version better than the whites, because over time a lot of dirt, sweat, etc. accumulated on the remote, this can be seen in the dark a lot less.
