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!
