The game has a close-zoom street view of the\n          cities, and when you scroll around it you can see a steady stream of\n          cars driving through the streets. Maybe 20 or 30 tiny sprites at a\n          time, but they navigate the road network, queue behind each other at\n          intersections, and generally look like a living city. Yes, it was a\n          bit buggy because sometimes they would drive through each other, but\n          it was good enough to just give some sense of life to the map. All\n          that on a 25 MHz 386 CPU.",
