Raid on Bungeling Bay was a super shoot ‘em up where you bomb these little islands. I had to create an editor where I could scroll around and create these little worlds to bomb. I found in playing with the editor that I was having a lot more fun creating these worlds than I was blowing them up. After I finished that game, I started kind of playing with the editor, and I started to add a little bit more dynamic to it. I wanted to keep traffic moving on the roads. I wanted to see kinds of dynamic systems operating. So I started reading about city planning. At first, I didn’t find the subject that interesting, but as I started developing very simple simulations of the theories I was reading, it became fascinating to me, because I had a little guinea pig city that I could sit there and experiment and play with.
