Yes. This is not tied to any score calculation just a hard number.
The displayed war reason is based on the highest impact factor in their decision making - in the case you shared it is the benefit vs cost/risks calculation. However, war fatigue (experienced costs / losses), war duration, prisoners, risk for the clan making a decision, any active tribute and the distance to an enemy also tie into it (and have their own texts associated with them).
IIRC there can be some slight variations within a single category as well - f.e.
They are stronger, but have great value | The {ENEMY.INFORMALNAME} may be strong but their lands are rich and ripe for the taking. |
We are stronger, we can take value | Right now we are stronger than the {ENEMY.INFORMALNAME}. We should strike while we can. |
So you say that there is hard 20 day of peace before a faction you've been at war can declare it again?
So thats not my experience at all.
Just this play now this was the scenario.
I'm with Battania as a merc mind you.
Battania and Vlandia at war for some time, but not excessive.
Western Empire declares war on Vlandia.
Vlandia offers peace to Battania.
2 days after peace Battania declares war on Western Empire.
Vlandia and Western Empire declares peace.
3-5 days after Vlandia declares war on Battania.
So in 8 days..
This "just isnt fun" imo
My guess is that Vlandia didnt like to pay the tribute they where forced to after Western Empire declared war on them.
Then since Battania got into war with WE, Vlandia figured "we shouldnt pay this much tribute".
Overall the roll to get peace without haveing a 3rd party involved is too high imo.
There should be peace after some time regardless, cause of "warfatigue".
The current system "to be blunt" is not good enough for the way I play.
Thus adding in a real hard 30 day peace that actually works, would do wonders.
In general maybe dial down the warmongering.
I mean inciting war is quite easy even if the other lords of the realm dislike you for it(but thats easy to fix relations with them if need be)
Inciting peace on the other hand is harder.
Beaten kingdomes, instead of going for peace will just hire mercs, until you've defeated them to a state where they basically "cant recover from in the long run".
The more land your capture the less intrested are your lords in peace(thus it kind of acts like a snowball effect, by haveing more peace, you could dial down that effect aswell).
