==From the developers:==

===AI Diplomacy Overhaul===
* Smarter Tribute Decisions: AI is now significantly less inclined to give in to tribute demands from weaker nations.
* The AI now weighs the military cost of crushing the demanding nation against the value of tribute and delays to its strategic goals.
** This change fixes unintuitive behavior where AI nations would easily appease others, even when stronger.
* AI’s rationalization of accepting tribute in the form of improved relations reduced further.

===Improved AI Behavior===
* AI behavior now reflects military strength more realistically in tribute negotiations.
* Tribute demands from the player are now auto-rejected if the AI has at least 75% of the player’s military strength.
* AI will only initiate tribute demands if their military is at least 2× stronger than the other nation.
* Gift value declines the more you give to prevent easy manipulation of Nation relations.

===Tribute Mechanics===
* Increased Cooldown: The cooldown between tribute or similar diplomatic requests is now 25 turns (up from 10).
* Higher Consequences for Failure:
* Penalty for rejected tribute demands increased from -100 → -250.
** Tribute rejection now carries a more meaningful diplomatic cost for players.
** Reduced Reward for Success: AI nations now grant much smaller diplomatic boosts when accepting tribute demands, representing a more rational stance.
* Difficulty Level Adjustment: Tribute acceptance is no longer heavily influenced by difficulty setting. On Easy, AI no longer automatically accepts demands.
* Fixed bug where the AI wasn’t looking at all of the items in a proposal.
* Fixed bug that could result in the AI always rejecting a demand tribute proposal.
* Balanced AI so that if the other nation has a lot more military power than the other then it is especially inclined to accept a demand tribute request.
