I'm intrigued by the logistics of getting that many cities built at optimal speed, in a situation where food's the limiting factor and cash seems pretty close to unlimited (never thought I'd see a Civ3 strategy that looked quite so Civ2ish). before you get to the point of being able to ship chain, what sort of balance are you using between settler production and worker production ? Going by the healthy-looking road network in the earlier screenshots, and on the assumption that if you're using settler pumps in the centre of that empire, some investment has gone into speeding up their routes to unoccupied land - that victory screenshot's just a little crowded to really look closely at the roads.
