I like to think I'm pretty good at what I do.

Rocket science has been mythologized all out of proportion to its true difficulty.

It's nice to have a game that sells a million copies.

Sometimes, the elegant implementation is just a function. Not a method. Not a class. Not a framework. Just a function.

Focused, hard work is the real key to success.

I wanted to remain a technical adviser for Id, but it just didn't work out. Probably for the best, as the divided focus was challenging.

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.
