Let me know what your opinions of this sort of diplomacy system. I originally came up with it after seeing all the shit with the CB's in EU5 and other paradox games, but I think it could apply to Total War Medieval 3 since they appear to be starting from scratch, and I know from experience that old Total War Medieval and Shogun 2 diplomacy is dogshit
Basically, we would have 2 types of casus belli/war declaration reasons
Justified Casus Belli: casus belli which either does not reduce reputation or can add to reputation / diplomatic standing with other nations
- Enforcing rightful/former claims (conquer a legitimate claim you once held or starting territory)
- Protecting citizens (retaliation for attacking merchants, diplomats, cardinals, princesses, etc)
- Enforcing broken treaty obligations (covers alot, breaking vassal agreements, trade protection, blockade, violating truces)
- Retaliation (for unsuccessful/successful: assassination, abduction, raids, ambushes...)
- Enthroning/Restoring foreign claimant (putting a leader on the throne of a foreign nation, or occupying a certain amount of territory of rightful land on their behalf)
- Expel foreign army from rightful territory (punishing an army for moving through territory without permission)
- Holy War (conquering lands from a heretic or foreign faith)
- Called in by Ally (sounds just like it reads)
- War to check belligerent conqueror (becomes available when a nation becomes a certain size/province limit, or perhaps even conquest speed)
Unjustified Casus Belli: casus belli which objectively damages reputation and lowers diplomatic opinion
- No Casus Belli (attacking without any justified reason)
- Breaking treaty obligations (sounds like it reads)
- Holy War (people from the defender's faith will see it as unjustified, but not those who share or don't have the faith)
- Exposed false flag (In my opinion, you should be able to fabricate false-flags, and a successful one will create a justified casus belli, but an unsuccessful one + declaration of war should cause the penalties)
- Deposing pious head of faith (mainly for catholic nations)
You guys can probably see the paradox-isms, but I still think they could work for total war. I do think total war should focus significantly less on the strategy aspects of course, but diplomacy always annoys me in the older games.
Anyhow, what do you guys think?
