Even John Carmack is always talking about how great the Xbox 360 sdk is, how easier to develop Directx became (he was a famous OpenGL proponent..).. he's going more crazy about developing crap for xbox and java phone games than making a new FPS revolution, he's disappointing.
While I have a great deal of respect for Carmack, who is obviously a very talented guy, he's done
precious little for the games industry beyond legitimising the graphics whore, and proving that mass-market success in the games industry can be very profitable for a select few people.
Well, maybe that's selling the guy short a little, but beyond Doom's sheer awesomeness (luck?) and Quake's moddable engine, everything else has just been graphics, graphics, graphics.
