The AI seems very reluctant to offer peace treaty even when starting the war and after loosing most of its territorry and ships.
I think there should be a much lower barrier to the offer being triggered when the AI has declared war on someone else (especially the player) as:
1. This would mean that the other faction probably is not that invested in the war (busy with other things - or wars) and woudl accept
2. Offering the peace and payment in exhange early on makes it much more probable for the other party to accept due to above and thus give time for the agressor to recover from its losses after their bad decision
3. Offering the payment when the faction is still strong does not put such a burden on their budget (though they are way OP in this so prboably never does)
4. The player is motivated to accept as else they are forced into eliminating the other faction entirely which leads to unwatned combat, tedious mockup and then instant win
Thus for their own enjoyement, most players would accept and concentrate on whatever they were doing before (even if it is preparing for war with that faciton
) and enjoying the reward for the victory by recieveing due payment. This would of course prolong the lifespam of all empires and the game itself while those players who would like to put an swift and agressive end ot the game can still choose to do so and ignore the offer
Example: I had a gear game going on assimilating all minor factions but avoiding conflict with a mayor empire that was 2X the size and pop of mine and technologically way more advanced. I was looking forward to finalyl a game with end-game tech involved to decie the outsome but jsut as I was gearing up they have declared war on me - so far this is perfect
But then I beat them in 10:1 occasion and started to also take their tech and roling out ships with equal level. At this time I was expecting the AI to offer a truce and payment as they have suffered heavy losses, a bunch of their system were facing imminent invasion, but still had a powerfull striking force which I wanted to avoid confronting directly. I wanted to take a truce had it been offered as I had fun in the battles but didn't want to push my luck and risk ending the game, but continue to tidy up my planets and modernise the fleets. Would have been a win-win scneario but withouth an offer the AI is forcing the game to end on the player.
