Well, I just had a game recently. I was started by Alexander and Rome. Never denounced them, all green diplo modifiers and guess what? They're just denouncing me left and right. Is this simply apart of the particular Civ's AI to declare war for no reason or something? I just want to know, why would the AI DoW when there are all green diplo modifiers? It seems a bit illogical to me. For no reason at all, Rome and Greece just keep DoWing me. And what's even worse, they won't accept peace. I was just playing as Germany. Does the AI have some sort of "auto-hate" for certain Civs? Anyways I'd really like to know why. It's a bit unsettling when the AI declares war for no reason at all.
