The type of game makes a difference as well. "Doom 3," "Half-Life 2," and "Halo 2" are three of the most anticipated upcoming games among Western audiences. Don't expect them to do well in Japan, however. In fact, they will have two strikes against them even before they land on the docks. All three games are, in addition to being violent, played from the first-person perspective. Such first-person perspective shooters (FPS) are big in the West, but have never really caught on in Japan. And few violent games sell well there, either.

Apparently the problem with quality consoles selling is due to their sphere of influence. GameCube seems to have only “Japanese” games and XBox has only “American” games. PlayStation provides both and therefore seems to be more popular. Of course consumers apparently don't mind crappier design, crappier price, crappier controls (multitap in specific), and crappier performance.
Here's hoping GameCubeNext and neXtBox both kill PS3 at the register... (Oh did I get off topic?)
