I like making lists, so here we go:
Short Version:
On Relations:
On Diplomatic Exchanges:
Feature Wishlist:
-Option to tell the AI to declare war or make peace. This is for us to babysit the AI when it’s making dumb decisions, but if the AI is fixed then imo it’s a little redundant and exploitable.
-Option to break off protectorate peacefully. Right now protector and protectorate can only break their relation by war. Also, you should be able to force someone else to release his protectorate.
-Option to restore a destroyed/emergent nation in your lands.
-Option to ally with foreign revolutions and re-emerged rebels
Any other issues you've had with diplomacy that I left out?
