Changes

The main selling point of the Wii - motion control devices relying on gyroscopic sensors to detect motion, and an IR sensor plus a "Wii Sensor Bar" on the top or bottom of the TV screen (which is just 2 red LEDs, and you can easily even use two candles on each side of the screen to get the exact same effect) to detect the screen and simulate pointers. Optionally, a nunchuck with an analog pad can be plugged to the Wiimote, and it also has its own gyroscopic controls. Some other, yet less common add-ons may be plugged in too.
