Beaut... And lovely terracotta!
Important question though... is the game (I'm on PtW) hard wired to just 5 city types? Do you know if it can it be increased to take more, and give a Mod/Scenario the oportunity to use your variety of various city/town graphics?
To give you an idea, I'm working on a mod with 30 civs, but so far have to pigeon hole them to live in just 5 domestic variations... they're going to get restless, surely!
