The barbarians are fucking relentless in higher difficulties. They get beaten easily but the fuckers are always buzzing around breaking my balls. It's barely 120 BC and I have destroyed more camps than I can remember. Ironically, I'm spending my ass off on my army and the loot from the camps is the only thing that keeps my economy going. And this was the game where I was supposed to not be a bloodthirsty monster for once and go for a diplomatic victory. Such is life.
