The AI seems more logical now
Yes and no as in yes that they do take more consideration in diplomacy now. No in that most seem to be dreadful for warfare, which is pretty much against historical terms of speaking.
This is my experience in my Europe map after three BNW games
England & Celts: I usually play the map for Renaissance style games but included the Celts a while ago to prevent England from becoming too powerful without enough competition. While in G&K they always tried to exterminate each other (with success), the British Isles have gone silent. With the exception of one denouncement from England to the Celts nothing happened there.
France: Used to be the biggest warmonger in the map. They killed the Netherlands on multiple occasions and on a regular basis went to war against Spain. In these three games France did nothing besides capturing a small Portuguese city in France and plotting against England because Elizabeth found it funny to settle next to Paris. They didn't even bother asking others for going to war.
Spain & Portugal: Only in one game was Spain quite aggressive against Portugal and kept attacking her. She didn't bother Maria I the other games and Maria I didn't bother anyone else.
Denmark: The fearsome and warmongering Vikings went pacifist and became best buddies with everyone nearby.
Sweden: See Denmark
The Netherlands: Only showed interest in aggression in one game by searching for aid to start a war. But the lack of support prevented them from actually going for it.
Germany & Austria: They usually didn't go well together and fought plenty of battles in the past. They do not seem to be bothering each other so much anymore.
Poland: Shows interest in warfare but only started one war against Austria because of my participation. Result: Poland didn't bother to send troops while I captured Vienna which was guarded by one composite bow archer and lacked any walls: The Habsburgers had no army. Nearby Bratislava supported and nearly sacked Vienna - imagine a CS performing better than a civ. Poland was hated a lot for just that single war while the only thing they did was organizing it.
Byzantium & Ottomans: The Byzantines always had difficulty surviving against the Ottomans (thankfully, making Piety available in the Ancient era finally got them working on religion so I don't have to turn on any mods to support them), also (in the past) with the Huns bugging them from the North. Byzantium and the Ottoman's near proximity always led to tensed diplomacy. Now they both get along with each other up to the point of making declaration of friendships.
The Huns: The mighty Huns used to be a bugger for nearby civs. Now they only pick on CS.
Mongolia: Went pacifist
Russia: Went pacifist
Arabia: Before G&K had a bit too much space and profited greatly from it, while usually not bothering to fight the Ottomans. I gave them and the Ottomans new concerns by adding Assyria to the area. Unfortunately for Arabia they've had a hard time surviving. One game they got exterminated and that led to a global denouncing and cooperated warfare against the Assyrians.
Morocco, Songhai and Zulu: To keep North-Africa occupied and the civs on the European side of the Mediterranean I also added the Songhai and the Zulu far more north than they should be. The results are interesting: one game Shaka went pacifist, one they nearly destroyed Songhai and the last one they bugged Morocco. Songhai went to war against Morocco once.
Venice: Played them in every game and I had no issues with anyone. Perhaps the combination of the Alps and few settling areas demotivated anyone from trying to attack me.
Despite the map has gotten more crowded with civs and CS, warfare is almost non existent and increased the dullness of playing on my map a lot. I want my warmongering AI back!
