To be fair, Caste System is a (re-)addition of my modmod and not a civic in regular DoC. Also I imagine that pre-industrial UHVs are quite a bit harder than later ones as I buffed later buildings and nerfed earlier ones. In fact I failed all my own attempts at an Indian UHV in Dawn of Knoedel, no matter the civics. IIRC the only UHVs I did accomplish in DoC were Egypt and Babylon, but only because I played them so often since they are rather short games.
I hope I can get some work done on DoK during the easter holidays, but my failed attempt at compiling DoC's DLL a month ago really stopped me in my tracks for a while.
Oh, I didn't realize how much you had changed! I've also completed Egypt and Babylon, and failed with India. I'm attempting Russia, but I've fallen far behind in tech... I followed the 1.12 UHV Paragon strategy from JustAnotherNerd to just focus on stealing techs through espionage. If I was ever going to try the spy game, it was going to be with Russia Did you change much with espionage/tech stealing?
