No, you cannot force an AI to make peace with another AI. You can make an AI go to war with another AI by making an alliance and then declaring war on your target, your ally AI will join your war. But you cannot force two AIs to go to war with each other with you staying out of it. That's a good change because it was way too big of an exploit.
Forcing peace though... Wouldn't play without it. I don't like the AI's killing each other off
Deal with it. Or just intervene militarily - put your troops in between their firing lines and slaughter them all!!!! muahuauhsdhj
If you want to ensure peace, you must conquer them all. When you control the entire globe, and unify the planet under your benevolent rule, then you will have true peace.
There should be some diplomatic option for trying to bring two AIs closer, as long as the player is at least cooperative with both. Something like:
- Make peace if at war;
- Become neutral if sanctioned;
- Cooperate if neutral;
- Become allies if cooperative;
Each try would need a time gap, in order to avoid instant leaps from war to alliance. Situation could deteriorate in the meantime due to respect loss between them, ruining the player's effort. Also, peace would need a time gap between when the war started and the when the mediation try happens.
Correct me if I am wrong, but I have impression that human like to influence AI
but if AI or game system influence human in the same way that human can. It will become restrictive in human point-of-view.
If runaway AI do capable of enforce truce between player. Some would fascinated by it, but many more will complain.
I also miss the ability to give the AI control of a city I don't want, instead of having to keep it or raze it.
