I am also wondering how the total amount of payd tribute effects the kingdoms over the course of a playthrough. I still think a predetermined total amount over x time is A more logical way.
Now declaring war is the only way to stop paying tribute.
Yeah infinite tribute on its face seems like an odd system, risks people winning in the bank rather than on the battlefield.
I dont fully understand war calculations in depth. But currently it seems like tributes work as a grudge system -- kingdoms look to reduce the tributes they are paying, this leads to some behaviour that is logical for the tribute system but is odd from a gameplay perspective. Namely short negotioation type wars.
I have seen this play out quite rationally (as far as the system is concerned) as a merc for NE I saw them enter into 3 different wars in turn to reduce tributes they were paying from 1000 down to paying 300. These wars were quite short not enough time for me to even move to the front on one of them. But succesful wars in terms of tribute. During these wars with various kingdoms, SE, BA, and WE the whole time NE was paying a wopping 3k from a very early war with Khuzait, total pay out around 270k. So from an early war where no territory traded hands Khuzaits are subsidised to the tune of 270k to fight wars with their other opponents.
So you can see in a hypothetical situation a dominate kingdom could end up collecting tribute from most of their neighbours. Which provides continuous motivation for those kingdoms to declare war on the stronger kingdom.
But how does that play out in practice when the dominate kingdom gets war declared on them from multiple kingdoms. I know there is code to encourage kingdoms to not fight multiple wars atleast to some extent, is it only the strong kingdoms who get these peace deals though?
Do they actually recieve the tribute in this situation because they are stronger, or does the fact they are the ones seeking peace bias negotiations so the strong kingdom fighting multiple enemies end up paying tribute.
So while you expect it to be the strong kingdoms collecting tributes motivating the weaker kingdoms to go to war with them.
The tributes could be a result of historic lopsided 1v2 war negotiations. Leading to a strong kingdoms holding a tribute grudge against a weaker kingdom.
This grudge type system has it merits I think. I just agree that after a set time the money part of it should end as to not be a "win more" mechanic.
So while this grudge value could persist untill the next war re-negotiates it, the part where money changes hands could end after 30 days (number pulled out of butt) as to not pin weaker kingdoms getting drained by one faction and being at war with others targeting them for their weakness.
