Nothing that I know of. It might change in the upcoming Civ 5 patches, at least I hope so. Global modifiers I've been thinking... a lot... and perhaps Afforess could answer me if it would be possible to add new global feature just like happiness and culture are? What if instead of culture points, you'd accumulate something like political/revolutionary/stability points that would be used for social policies? Culture points could be then used for other things, like expanding borders (it could lower the price of tiles) and bringing immigrants towards your country, and finding culture related techs (art, music etc) and making tourist attractions... what else could be culture used? So we could have following global modifiers that empire produces: gold science culture stability religion happiness health electricity (this could be strategic resource too) Improvements In Civ 4: RoM we got improvements that upgrade over time. I want to bring this same feature to Civ 5 version but I had planned to change the system a bit... instead of building Mine and it upgrading to Shaft Mine and then to Modern Mine, you would now build Mining Colony which upgrades to Mining Village and then to Mining Town etc. Farm could go from Tribal farms (farm+cottage), Communal Farms (farm+hamlet), Medieval Farms (farm+castle, crop rotation), Modern Farms (farm + town, fertilizers + pesticides + machines), Vertical Farms (modern suburb with vertical farm skyscrapers). Some techs obviously would increase the benefits of each improvement type just like in previous RoM. Basically each improvement represents what that tile produces and what kind of people lives there that keep the production running on that plot. What do you think about this?
