I've seen few times when AI nation has +90 war score, but they still prefer white peace, even though they could've got a lot of land. What is the point of that?
But what determines their "personalities" if I have used CKII to EUIV converter?Some countries are more aggressive based on their "personalities," like the Ottomans, who were quite the expansionists in history. Russia also tends to go very deep into China because they have very rich provinces that are easy to take. I think other European nations have been toned down since 1.0; when EUIV was released everyone was blobbing like madmen, even the HRE minors.
Maybe they don't have the diplo points? I've always wished you could just go into negative diplo points to make peace deals, maybe that would help the AI.
