Nintendo Wii

To start of here are the basics, the main point of the Wii and the reason it is 'Uneek' is because it has accelerometers in the controller which gives it the ability to since movement, i.e. it knows when you, say, swing your arm, which opens a world of possibilities. The racing games for the Wii don't use arrows or a joystick, they use the accelerometer so to steer you tilt the controller. But if you don't want to have to move around just to play a video game, the Wii has ports for gamecube controllers and memory cards, so all you have to do is pop in a gamecube disk and start playing, that's it.
Well that's pretty much the basics, I'll post later about the more complicated stuff, like specific games, and if you don't own a Wii and are thinking about getting one I would recommend it.
