Description:

This mod focuses on improving diplomacy, but especially on enhancing the diplomatic relationships of the AI, both AI-Player and AI-AI.

Thousands of new entries have been modified and, most importantly, added to enable the AI to engage in fully developed diplomacy. Many of the tables were severely truncated and had missing or nonexistent entries for many factions. Additionally, the AI’s priorities and diplomatic handling have been fine-tuned.

I will try to explain the most relevant changes, but due to the size of the mod, not everything will be detailed. This is a mod I have worked on for a long time, and I will provide three versions: this one as the main version oriented towards the vanilla game, and two more that I will leave in the comments below.

-The responses to diplomatic events have been readjusted and expanded to be more coherent and to redefine penalties. In general, minor actions no longer have such a significant impact on reliability duration.

-Money has a reduced impact on diplomacy. Diplomatic decisions can only be influenced by money up to a maximum factor of -10 (approximate value), but it will also require less money. Similarly, favorable deals will grant less money.

-Trade agreements have reduced penalties, and more treaties are allowed before penalties are incurred.

-The duration of penalties for treaties and treaty breaches has been reduced, as well as the duration and penalties for confederations (among other changes)

-The number of treaties the AI can handle has been increased, the priority for treaties based on the AI’s proximity has been raised, and confederations are now easier to achieve.

-Actions that please factions have neither penalties nor bonuses, while those that displease them generate double the penalty.

AI Diplomatic Priorities

I’ll start by saying two things: first, this was quite poorly implemented in the base game and many things were missing; and second, it’s going to be difficult to explain.

These tables are increased between 5 and 7 times, this implies that all features must be prioritized and evaluated to be able to carry out transactions that cannot be carried out beforehand.

There are two main components to this: the generation of priorities and their evaluation. Therefore, I will explain it by outlining the order of priorities and the level of difficulty:

-FORM CONFEDERATION P:10 E:Dificult
-DECLARE WAR ON NEARBY FACTIONS P:9,5 E:Easy
-DECLARE WAR ON FACTIONS I DISLIKE P:9,5 E:Easy (The priority decreases with distance)
-DEFENSIVE ALLIANCE P:9 E:Very Dificult (The priority decreases with distance)
-MILITARY ALLIANCE P:8,5 E:Very Dificult (The priority decreases with distance)
-MILITARY ACCESS P:8 E:Medium (The priority decreases with distance)
-TRADE AGREEMENT P:8 E:Medium
-UPGRADE TREATIES P:8 E:Medium
-OFFER VASSALAGE OR CLIENT STATE TO ENEMIES P:8 E:Very Dificult
-BREAK TREATIES WITH DISLIKED FACTIONS P:8 E:Easy (The priority increases with distance)
-REQUEST BREAK ALLIANCE WITH DISLIKED FACTIONS P:7,5 E:Easy (The priority increases with distance)
-PEACE P:7 E:Very Dificult
-NON AGGRESSION PACT P:7 E:Easy
-DEMAND VASSALAGE OR CLIENT STATE FROM ENEMIES P:6,5 E:Very Dificult
-REQUEST BREAK TREATY WITH DISLIKED FACTIONS P:6,5 E:Very Easy (The priority increases with distance)
-TREATIES WITH ALLIES OF ALLIES P:6,5 E:Medium
-TREATIES WITH NEIGHBOURS P:6,5 E:Medium
-REQUEST ALLY TO JOIN WAR P:6 E:Dificult
-Minor factions cannot confederate with other factions and cannot have vassals.

Keep in mind that the values for "P" (priority) and "E" (estimation) are indicative and not the actual values used in the mod. The estimation reflects how well you get along with that faction and the usual factors that affect treaties. Consequently, the AI will:

-Declare war on neighboring factions it has poor relations with.
-Form alliances with friendly factions.
-Rarely ask you to join a war or attempt to make peace (peace in Total War: Warhammer? Don’t make me laugh).

However, you will especially notice that it interacts much more with other AIs, potentially gaining more allies or enemies than you.

Lastly, I am providing two versions of this mod, which include everything from this one but are designed to create faction wars or super-faction wars, just use this one or one of these.
Diplomacy Mega Factions Wars
Diplomcy Factions Wars

I recommend that you use my mod Diplomacy For All In order to unlock all diplomatic options for all factions.

Can use Unbreakable Alliances if they don’t want to deal with alliance breakups due to factional conflicts.

Can use Confederation for Warriors of Chaos and Tomb Kin If you want these factions to be able to confederate.

Finally I created a paypal account in case anyone wants to thank me for my work in this way

Subscribing and adding to favorites is fine, but if you want other people to see the mods you like, after trying the mods if you like this press 👍. I see mods with 3000 downloads and only 80 reviews, that makes me☹️. People who are dedicated to modifications will appreciate it. Thank you.

Remember to take a look at the mods in my game collection, I use them all, but even if I only use a few the game will improve a lot, and it’s completely modular.
