Smith, on crafting environments:

"We deliberately don't make pathways, right?"

"If we make an environment, we try to make it as plausibly as possible. Like, where do people get to work? How do they get to work, down this street or that street? Where they take the garbage—you know, it's a very plausible environment. And then we put, you know, AIs in it or goals in it or whatever, and then we let the player move toward that however he wants."
