Nikkei_Simmer's Stupid Questions #3 - WCIF - A Small World (256x256) with only 9 lots:

@Mikezumi, I've been trying to figure out how to eliminate immigration (other than building a "wall" ~sorry, bad joke~). I've tried the NRAAS Register and SP but still haven't been able to eliminate ALL sims (service); I've managed to get to the point where no Townies are generating...all the rest are service NPCs and they keep spawning...and I have to keep killing them off. I don't know how @TadOlson manages to keep the service NPCs from spawning in the games and I'd like to pick @TadOlson's brain on how to do that.
