Why is it successful?

(1)Human Computer Interface breakthrough VS. Graphics rendering power
(2)Make the player pie bigger: including the traditional non-game players: such as grandparents and grandchildren, not just youth groups.
(3)Traditional game players are usually lonely in one room, with networking connected to outside world only, while theWiiincludes everyone in one game in one room (a social medium).
(4)Single-handed remote control, much less buttons and control.

(5)Good to "PLAY" vs. good to "LOOK"
(6)3D orientation and location control,added force feedback: vibration and sound,
