Quotes:

"We're trying to come up with very very simple rules that we can decompress into these elaborate worlds."

"We see that a lot with simulations, because we're always looking for very simple rule structures that we build into prototypes, and we just turn them on and see what happens, and then from there we will start modifying them, and it's very much the process of surprise and discovery, and it's so non-linear, it's so counter-intuitive, that it's very difficult to kind of have an end result in mind as a target and then shoot for that."

"It seems like on some level of complexity you wouldn't even be able to determine whether it was random, or there was a complex algorithm underneath."

"It's amazing how humans can see patterns in almost anything, and we're always searching for these patterns, even if they don't actually exist. And we've even engineered things that kind of bring us more into meditative, spiritual realms that in some sense are generative systems for the mind."

"Yes. Yes. You want to be on the cusp, where it doesn't sound random, but it doesn't sound too obvious and too predictable. It doesn't unfold like you would expect it to, but it doesn't unfold in an entirely unexpected and disconnected way, either."

"And this is very much the type of thing where you have no idea what it's going to look like when you build the rules. You turn it on, and it's always just a total surprise. These were actually developed in I think the forties by Von Oyman. Before he even really had fast digital computers to run them on, and another interesting thing about these, is how fragile they are."

"Sim City, which is one of the games I worked on many years ago, in fact is underlayed by just a set of very simple cellular automina like this, you know they have very simple rules for things like crime and traffic and pollution, and on top of that we lay all these nice graphics of cars, and factories and all that. But really underneath, it's a very simple grid system like this, that allows us to simulate things, and it took awhile to discover the rules, but once we actually put together a few simple rules, we got to systems where we were seeing emergent phenomena, we were seeing things like gentrification, just through the simple actions of the crime, land value rules. And stuff like that. And it seemed like it was a much more complex simulation than in fact it really was."

"So I'm going to show you a game that I'm working on right now that relies very heavily on generative systems, and it's called Spore. The rough idea was inspired by the Powers of Ten, which was a book and movie done by Charles Eames, actually done earlier by a Dutch screen teacher named Case Butler, called Cosmic View, but I'm sure you've seen this idea in the film or the movie where you have a guy in a park and it goes down to the cellular level, to the atomic level, all the way down to the quarks, and then it pulls all the way back to the planet, and the sun, and the galaxy. And I always thought it was a very unique perspective, and it was kind of missing the dynamics, I always wanted to see the dynamics on different scales, so that was part of the inspiration behind Spore."

"I can like put one little cell in the wrong spot here, and very quickly the whole thing just kind of goes to crap. That was one cell, and...and now the whole cycle's broken, these guys are going off forever in that direction. We can actually use these things for doing simulation. In fact, a lot of our games are built upon cellular automina at a very simple level, to simulate what seemingly is a very complex thing."
