About half the people at Valve have run their own companies, so they always have the option not just to take a job at another game company, but to go start their own company. The question you always have to answer is, 'How are we making these people more valuable than they would be elsewhere?'

The PC is successful because we're all benefiting from the competition with each other. If Twitter comes along, our games benefit. If Nvidia makes better graphics technology, all the games are going to shine. If we come out with a better game, people are going to buy more PCs.

I think that Windows 8 is kind of a catastrophe for everybody in the PC space.

I'm a handsome man with a charming personality.

The Internet is changing what entertainment and sports is. It's not just a few people authoring an experience for others. It's really growing out of what everybody does.

If you look at the requirements for just one piece, like art, from one generation of games to the next, it will change radically. You need people who are adaptable because the thing that makes you the best in the world in one generation of games is going to be totally useless in the next.

Ninety percent of games lose money; 10 percent make a lot of money. And there's a consistency around the competitive advantages you create, so if you can actually learn how to do the art, the design, and the programming, you would be consistently very profitable.
