Rivals - The Enemy of my Enemy is my Friend
One of the biggest changes to diplomacy in Europa Universalis IV is the new ability to designate up to three countries as rivals. Why would you want to have a rival? Doesn’t this just make the rival country angry at you? Yes, it will lower relations between you and the rival, but with an advantage too. Relations with any other country that has the same rival will improve and you can think about joining up to contain the hated So-and-sos. It’s the old “enemy of my enemy” thing. If someone has marked you as a rival, they will appear as your enemy in your diplomatic menu. We strongly believe this adds depth to the diplomacy system in Europa Universalis IV.
Secondly, the similar diplomatic actions have been grouped together into categories for an expandable list. Simply open a category to see what’s in there and close it when you’re done. Or not – it’s your list. To further improve this part of the interface, we have added two types of icons on those buttons. First there is a small diplomat icon on those actions which will require a diplomat to stay for the duration – remember that in EU4 you have limited diplomats and sometimes they will be very occupied. Secondly, for those actions where the AI has to accept or decline an offer, we’ve added a small arrow indicating the likelihood that they’ll listent o your overtures.You no longer get vague answers from the AI, but instead you always get a yes/no reply, and a detailed explanation on why they’ve declined your offer.
