The Xbox consumer is different as well. The PC lives in the den, and it is usually a dual-use productivity and entertainment machine. The Xbox lives in the living room and serves as part of the family's entertainment system. The PC interface is based on a mouse and keyboard. The Xbox uses a controller.
Many families own both a PC and a game console and play different kinds of games on each.
Stormfront's view is that we're designing games for game players, not for platforms. If some games move easily from one set of players to another, then porting issues matter. But many games won't move well between those worlds, so we shouldn't look at portability as an all-defining issue. But that ignores an important issue. I think the significance of all these new processors is that they represent a fundamental change in the way we make games.
