A regular problem that I have is that I'm always stuck in an endless rinse and repeat cycle of provincial revolts. The rebels more a nuisance than a real problem, but since I'm seeing that Carthage, controlled by the AI, is mostly of the same size and doesn't seem to incur in any similar problem, I guess I'm doing something wrong. And in my previous game as Egypt, AI Rome got really big and almost no revolts either. My strategy is to give some of the rights to the non integrated cultures like intermarriage, inheritance and so on and also developing the provinces with new cities and buildings that increase the pops happiness, but it seems it's never really enough. There is something I am missing?
