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.

At its best, entertainment is going to be a subjective thing that can't win for everyone, while at worst, a particular game just becomes a random symbol for petty tribal behavior.

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

Low-level programming is good for the programmer's soul.

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

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.

If you aren't sure which way to do something, do it both ways and see which works better.
