Quoting Frogboy, reply 19That is not true. They won't go after you unless their relations with you are neutral or less.
You sure the other Ai can't bribe them into war even if they are in good relations with me?
P.S. all my play experience has been on normal.
Indeed I'm fairly sure I've seen AI's that I'm friendly with declare war on me with phrases such as "I don't have anything against me, but X told me to go to war with you"
There are a number of things that I think could be fixed with how the AI currently handles declaring war.
1) During a non-aggression pact the AI shouldn't be able to declare war, it just doesn't make sense.
2) There are few things as frustrating as bribing the AI with 2-300 gold to get Tech/Economy treaties only for him to declare war on you next turn, the AI should get a huge diplomacy bonus after getting bribed (Maybe proportional to the size of the bribe) that tapers off with time to the default +1 after 10-20 turns.
3) Just like in CivV it would make for a much more enjoyable game if the AI gangbanged the Strongest player rather then the weakest.
4) On the subject of stealing things from CivV diplomacy, it would also be nice with diplomacy bonuses for long term treaties, long term peace, common enemies etc. Should also be diplomacy penalties for attacking weaker players, attacking your own faction, building a wonder that player wanted etc.
Quoting Fistalis, reply 16atter the AI will join a war against you no matter how good your relations are. Diplomacy is borked.
That is not true. They won't go after you unless their relations with you are neutral or less.
Also, World Difficulty above challenging means the monsters will go after you more than the AI. World Difficulty less than challenging means the monsters will go after the AI more than you.
I found this very confusing. There's an AI difficulty both under World Settings and under Opponent Settings. You're saying that the World AI setting alters the Monster aggresiveness while the Opponent setting alters the actual AI? You should really fix that tool-tip in the world settings then.
