that's the one scandalous thing about Nintendo this generation, even moreso than their offering of an overclocked GameCube
the QUANTITY of peripherals that someone has to buy when they focus on local multiplayer games-- four Wii remotes, four nunchuks, four classic controllers, and now four zappers... all at 40$ a pop, when they cost probably 2$ to make to Nintendo
THAT'S where they make their money, moreso than on hardware sales and even probably on software sales
