About the warsuccess thingy. I expect that war success for the opponent means negative war success for you. If you kill a unit then that is a positive thing, but if your opponent kills a unit of yours, then that is a negative thing. If you capture and then lose a city again, then that's a neutral effect on warsuccess. Is that correct?
No. Only war success counts, not war failure. But since there are two different peace values, yours and his, your success affects your peace value and his success affects his peace value, so it works out. I actually made a mistake above, the war succes value for peace is his success vs you not the other way around.
I didn't see a factor for war weariness. I know that it is connected to killing and losing units in foreign territory and capturing cities and nuking and getting nuked. So it resembles the warsuccess modifier a bit. But the main difference is that war weariness can only become worse during a war. Another difference is that a very succesfull war can lead to disastrous levels of war weariness. Even if you sign a peace treaty after a war has lasted so long that war weariness became crippling, then redeclaring war after a short peace period won't reset the war weariness. It will still be crippling and thus such a redeclared war is bad for both parties involved (assuming both have high levels of war weariness).
Crippling war weariness is a thing that should cause both parties in the war to want to end the war and stay in peace for a while. War weariness decreases only very slowly.
Right now, there is no factor for war weariness, you are correct. Adding one, might make these stagnating wars end.
