It's a good thing Doom 3 is selling very well.

If you're willing to restrict the flexibility of your approach, you can almost always do something better

The Xbox 360 is the first console that I've ever worked with that actually has development tools that are better for games than what we've had on PC.

I recognize that I possess a very special intellect, but at the same time, I recognize that I'm lacking in a lot of areas. But being well-rounded is greatly overrated.

The Escalation programmers come from a completely different background, and the codebase is all STL this, boost that, fill-up-the-property list, dispatch the event, and delegate that. I had been harboring some suspicions that our big codebases might benefit from the application of some more of the various “modern” C++ design patterns, despite seeing other large game codebases suffer under them. I have since recanted that suspicion.

Focus is a matter of deciding what things you're not going to do.

I really think, if anything, there is more evidence to show that the violent games reduce aggression and violence. There have actually been some studies about that, that it's cathartic. If you go to QuakeCon and you walk by and you see the people there [and compare that to] a random cross section of a college campus, you're probably going to find a more peaceful crowd of people at the gaming convention. I think it’s at worst neutral and potentially positive.
