The idea has a good feel to it, but there's several problems. If half of the soldiers are ejected and the rebels stay in, that means the rebels have the advantage, and that sounds more like a military coup than anything. I think just taking the stability thing from RFC and comibing it with Revolution would be simplier and more fun. What Scilly Guy said, I like his idea. If a king dies with no heir, than there might be a small civil war. If a dictator dies, than there'll be a LOT of problems. Also, with the princess thing, I like it =P. Also, If two nations become friendly enough with each other, they could combine their kingdoms, like in Permanent alliances.
