How does Rage fit into Id's history? Bethesda attempt to explain in a new video, which you can see below. There's some new Rage footage, but also footage of a bunch of classic Id games, providing a bit of perspective on where Id went after Wolfenstein. The video has Carmack, Hollenshead and others doing a bit of talking, and there's a crumb of insight on the megatexture tech, and how that will - apparently - be exploited properly in Rage.
Rage is starting to look interesting, I think.
