Why can the Wii sell the same 3 games forever....?

[The Anarchyz]

Simple, Wii wouldn't be selling like it does if it wasn't because of the casual-4

-Wii Sports
-Wii Play
-Wii Fit
-Mario Kart Wii (this one is not only for casuals, but they love it)

Wii Music was the 1st one to not make an impact...
