I had a question about towns in this game. I noticed that there is a "town" tile improvement in the game, just like the "village" tile improvement, but I'm not sure how to get my workers to make one. I figured it must be the way Civilization 4 does it where you have to work a hamlet tile before it'll grow into a village and so forth, but it doesn't grow either. Am I missing a technology?
Towns are the Custom House improvement - they're made by Great Merchants.
