How exactly is the casus belli system any different than what we currently have? I always declare war on people for one reason or another, wether it be religion, resources, keep other civs happy, or just pissing me off. This works the same with the AI.
Casus belli is just a flowery way of saying why ur going to war, but we already have a system where the AI says why there going to war with you.
We already have a white peace, your version is just changing the name.
I find war score is too one-sided with decisions.
We don't need to shove paradoxes systems into every other game.
It isn't just a 'flowery way' of doing it, it would be hard-coded into the AI to actually make those reasons you go to war mean something. At the minute it seems the only difference is who started it and wether you take the last city. CB's would make starting wars more of a decision, I would like to see the most 'unjust' aggression face stronger diplo penalties than now & maybe even support from other civ's when using a CB to re-take your lost territory, not neccessarily military support, war subsidies or diplo modifier boost maybe.
