Wow, so nice to hear from the original developer!
Having played with a little simulatiom, I now intend to replicate a cleaner, better version of micropolis. The intention is to port the simulation engine as thoroughly as possible, and then provide a UI in emacs.
...of the unix version. That's the one i played back in the day!
RMS says he would appreciate you contributing it to emacs! It's more fun than psychoanalyzing yourself with Doctor.
Well, while i am porting micropolis, there is always tetris!
