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

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.

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

Ultimately, all I wanted was for players to feel like they were in the real world. I wanted them to be able to apply real world common sense to the problems confronting them, and I thought recreating real world locations would encourage that kind of thinking. There's also just a real power, a real thrill, when you fire up a game and see a place you've been or want to go, and then get to do all the stuff you WANT to do there but know you'll get arrested if you try! If that isn't the stuff of fantasy - far more than exploring some goofy dwarven mine or alien spaceship - I don't know what is!
