What about rebellions against their current lords? Instead of needing the stats to be super low, maybe if they're too peaceful, the peasants start to get some thoughts of "independence" and start wanting freedom.
Yes, that's exactly what we tried.
Think about it for a minute, Bronnen. What happens if your regions start revolting? Does that put you in a good position to go to war? Or does it mean that if you try declaring war and fighting battles, you'll end up getting the floor mopped with you and lose even more?
Any kind of "regions have trouble if you are at peace too long" system is going to be guaranteed to set up a lose-lose situation for anyone who falls afoul of it.
