@Zombie22, this is old and all, but that is exactly what I did back in like 2014/15 in a personal mod I made for EU4. I called "Ming Unchained", and what it did was run an event for Ming. It checked all neighboring countries to see if they had claims in them. If they didn't have claims, a country was selected at random, and Ming was given claims. If Ming had claims, no claims were given.

This resulted in a turbo Ming that was basically a "big bad" for an end game showdown of sorts.

I later applied the same thing to Ottomans. That was a bad idea lol.

Played on shattered (battle royal). First 5 years AI was docile, in 1841 became warmongering. Will have to test again with economic AI mods turned off, since AI seemed to want to build steel mills and lose a ton of money subsidizing them.

(these noobs saying you can increase aggression obviously have never observed a game) --mods are needed for this.

This mod just doesn't work. The AI is just as aggressive as in the base AI set to "High" on aggressivness.

Adding cores may be a simple and crude approach, although it can be anticipated that AI will expand completely outside of history. And Germany's unified log scope may get out of control

If you were to increase the AI's parameters for choosing a political goal to expanding borders, you could make the AI not adopt a passive policy (defending borders and the like) - I would also check the settings. In the settings, there is an option that changes the AI's aggression - generally and towards players. You can slightly change this setting so that aggression in general is at the highest possible level.

As you noticed: Each AI has random policies that it chooses. If it were to choose expanding borders more often, there would certainly be a lot more going on.

Anyone else noticing the AI have barely any aggression on normal earth? I've tuned up AI recklessness and aggressiveness if they have certain agendas like expand core territory or maintain balance of power. However, I still don't see many wars. I believe it works well on shattered world because all the AI have their strategy set to expand core territory so they are super aggressive early on.

I don't think in normal earth the AI care if they have expand core territory on since they usually already hold all their cores.

Let me know if any of you guys have an idea how I could make there more wars. Maybe I could give every nation cores to every province. I could also make the AI more prone to hating each other and establishing rivalries. This may work well because in my games, AI only declare war on me if we have horrible relations.

@France There used to be a mod that didn't remove any buttons, it only changed the score that determines whether a given AI actor is afraid. However, this mod was a long time ago and has been removed. If you found the file responsible for these parameters, you could add it less invasively. Just keep in mind that since the beginning of Vic3, there was only one mod that changed it. Therefore, you need to search a bit and you can do it less invasively. - Good luck!

@zombie22 This mod primarily focuses on aggressive AI behavior. The AI would be harder to beat if they integrated everything. There was a mod that used to do this but is now outdated. Hopefully they update soon. Otherwise I'll have providing an updated version of the mod to my road map as this seems very important to game balance.

@kacpi_tv I'll add it to the road map. Sounds possible to prevent AI from yielding in diplomatic plays. For human players their back down button would need to be removed.

Will AI be more willing to integrate regions?

Could you add unyielding to both sides so neither side is able to back down?

Mod state:
Shattered World works great, have gone all the way to mid-game on it. Earth is a bit more interesting than normal, I've only seen early-game on Earth though.

Currently I believe the reason there aren't as many wars on the earth map is that small powers are scared to attack other small powers because they see a great power might intervene in the diplomatic play. I could make AI not care about the expected military power difference in a diplomatic play and it would make Earth more aggressive.

I could also attempt to make it more likely AI get aggressive AI strategies (not sure if possible), in my shattered Earth game I saw the Yankee state (east coast america orange nation) went on a rampage when it got the "expand core territory" ai strategy, they did 4 wars back to back, growing by tons of states. Let me know what you guys think!
