AI gang up? maybe. All games are different. I mean when you play a game and starting over, the next game will have a different situation, sometimes you can gang up with other AIs, sometimes the AIs will gang up on you, sometimes you won't notice any gang ups.

You have a nice list there. A good diplo system would be awesome. If Illwinter want to add something new, they must think about 2 things:

1. The weapon / armor system
2. The diplomacy system

PS. there was another game, with this AI request when he is in trouble: The good old Romance of the 3 Kingdoms series by KOEI. As I said those games had the best diplo model ever!
