Minor Diplomacy Tweaks
This is a lightweight mod that makes minor tweaks to diplomacy in the game:
– Makes AI less likely to form massive alliance chains by decreasing their willingness to form alliances as the number of their allies increases. With the mod, AI is unlikely to have more than 4 allies at a time. The mod doesn’t change anything about subjects or diplomatic capacity, just AI decision making regarding alliances.
– Removes favor needs from requesting military access, but makes AI less willing to give it out for free as to not make the "access purchase" action completely obsolete.
Completely safe to add and remove in an existing campaign. If added to a running campaign, it might take a few months to tick over for AI to break apart a massive alliance chain.
