One small thing I would change is make civics become outdated later than they do now. I don't know the specifics unfortunately, but in my game as Indonesia I have -15 stability for running outdated civics in 1485. I'm running Theocracy, Vassalage, Capitalism, Guilds, Organized Religion and Levy Armies. I'm assuming Vassalage and OR are the culprits? I don't think them being outdated in the 15th century, or the penalty being so severe, is very historical. Both these civics represent 15th century Europe pretty well imo. There's also the fact that some civs don't have alternatives to these at this point.
However, just a suggestion. If this is for balance or what-have-you then that's different.
