naf4ever said:A simpler way would be to just let people build anywhere like now. But make cities built on difficult terrains early on have max pop limits. Maybe 3 people for a place built on a hill without the proper technology, maybe 1 for a jungle. This way at too represent the little villages and settlements that people did have in places like those a long time ago.
this would then prevent so speedy cultural expansion as temples would either have to be rushed or take ages to build. It would mean people would settle good spots first, then when available techs are researched settle the "dodgy spots" (Y)(Y)(Y)
