The internet is super smart. If you do something that is cool, that's actually worth people's time, then they'll adopt it. If you do something that's not cool and sucks, you can spend as many marketing dollars as you want, [they] just won't

The programmers of tomorrow are the wizards of the future.

When I worked at Microsoft, I got to go and visit a bunch of different companies. Probably a hundred different companies a year. You'd see all the different ways they'd work. The guys who did Ventura Publisher one day, and then United Airlines the next. You'd see the 12 guys in Texas doing Doom, and then you'd go see Aetna life insurance.

The culture at Valve is pretty much crowdsourced. The handbook is a wiki. One of the first things we say to new hires is, 'You have to change something in the handbook.'

In order for innovation to happen, a bunch of things that aren't happening on closed platforms need to occur. Valve wouldn't exist today without the PC, or Epic, or Zynga, or Google. They all wouldn't have existed without the openness of the platform. There's a strong tempation to close the platform, because they look at what they can accomplish when they limit the competitors' access to the platform, and they say 'That's really exciting.'

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.

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.
