I've made huge progress on my Civ 3 mod! Like, huge huge progress. I managed to complete Africa. Now, granted. Africa is comparably huge to the rest of Europe and the Mediterranean. And it's very very very very broad strokes. But I got it working more or less the way I want it to. Which means I got Carthage and Egypt done, too, and also the Roman cities there as well.
And now? I've gotten Greece done as well! I'm working on Persia and it's all coming together. The map's probably like 50% done which means the mod will be much closer to complete. I do need to cross-reference my map with the Mesopotamian map, and other maps (Fall, Middle Ages, Napoleon), but it's actually coming together!
