Ah, the joys of games without autosave... there goes a few hours worth of building up the city, and I'd just gotten it to the point where it was making huge amounts of money, and I could start plopping down unique building left and right, and was finally about to start making a subway line, had three dams making about 300 MW power, a solar power plant, enough garbage incinerators that the landfills were slowly emptying, and other good stuff... Ah well, at least now I know where the problem spots for traffic starts to form, and such ^^;
