Culture victory is achieved by getting 3 cities at legendary culture. Which requires about 150,000 culture. That sounds like a lot, but when your base culture rate can be about 150 or so from population and wonders, and then your multiplier can get in the order of 500-700%, add in 100% culture from commerce and you can get as high as 2,000 culture per turn or more.
Anyway, I plan on removing culture victory eventually. Instead, if a civilization's culture is prevalent enough it can make cities across the globe revolt, leading to a domination/conquest win. This makes more sense.
The trick, however, is figuring out a formula for making cities revolt, since I'm going to have to use python to force cities to revolt.
I'm thinking ((foreign nationality - domestic nationality) / domestic nationality * 10 ) ^ (1.1 ^ (number of military units stationed + 1)), which means in a hypothetical case of 40% foreign and 30% domestic culture, for military units garrisoned: chance of revolt, it would be 1: 2.4%, 2: 1.6%, 3: 1.1%, 4: 0.7% 5: below 0.5%, which I'll make an arbitraty cutoff.
I'll look into the weird nationality thing. If you could provide a save along with telling me what version of the mod you were running that would be rather helpful.
Finally, when you beat the game on Prince, Ubik, what strategy(ies) did you employ and what victory did you achieve?
I've found the computer will assign a very high priority to Automated Assembly Plants, even though they can easily take 100-250 turns before they pay off. To that end I'll remove the advertised +5% production from them (they'll still give the production bonus, however the AI won't know about it and it'll try building more useful stuff). I personally enjoy building Hydroponics farms myself.
