Good stories are constructed, not found.

Creating a really believable world is just insanely hard

Games are not about being told things. If you want to tell people things, write a book or make a movie. Games are dialogues - and dialogue requires both parties to take the floor once in a while

If we're going to reach a broader audience, we have to stop thinking about that audience strictly in terms of teenage boys or even teenage girls. We need to think about things that are relevant to normal humans and not just the geeks we used to be.

As the story unfolded, the cast of characters changed to match it.

I remember having some problems with [the Deus Ex theme] when I first heard it and I was trying to figure out how to tell [Alex Brandon] I wanted changes. But then I noticed that I couldn't get it out of my mind. I was whistling or humming it to myself all the time. So I just kept my mouth shut and let it be. I think it's a highly addictive tune

I'm sure a lot of the hardcore folks are going to be up in arms and I'm really looking forward to getting into that discussion with them. I don't believe I'm compromising on my gameplay ideals at all. [But] any artist who doesn't want his or her work in front of the largest audience possible is nuts.

Half-Life is the finest implementation of a game on rails anybody has ever done

I'm sad but excited for the future.
