It's been a while since I've played RFC, and I found out the hard way that it is impossible to kill off empires before they can effectively spawn now. For example, when playing as the Maya, my old strategy was to found Huaxyacac as my capital, build up a catapult heavy army in preparation for the coming of the Aztec and smash them before Tenochtitlan could eat my resources. But I found that as soon as I was able to weaken the Aztec starting army, a 6 strength Jaguar popped up on top of the stack. A similar instance happened when I was playing as the Viking and attempted to kill the English so that I could keep Inverness, right when I was about to defeat them, Longbows began to appear out of thin air. I seem to remember the same thing happening with the Spanish in fighting the Portuguese, but from my last game as Isabella it looks like I was able to take them out somehow anyway. I don't know when exactly this happened, but it's made the playstyle that I'm used to much harder. What are the mechanics of this feature, and how do you guys handle these nasty foreign capitals that are too much of a hindrance to ignore when they spawn?
