I might have to go to war with Nubia in that game.....but she might reconquer it again
I hated how Chandragupta conquered Carthage in my America game (still unfinished) and the conquered CS has "full loyalty" to India. He even spammed two cities close to my empire and still has full loyalty for those. In general, I don't like the loyalty system. So much land is ignored by the AI Civs and I can't settled there without losing my cities.
So how does warmongering even work now? Does taking the other Civ's capital impact the loyalty in their other cities? Will their empire fall apart because of that?
