Diplomacy has become extremely odd. They don't trade extra luxury resources anymore (Not their final copy.). All their offers are terrible for luxury resources. A Civ I was friends with offer me 1 gold per turn for 3 luxury resources. Dealing wasn't silly in ancient era, but gets progressively worse. They just give up cities so easily in peace deals for unknown reasons. I know I'm winning the war, but to give up nearly their entire empire? I usually just take city states back to liberate them, which I'm glad they added the ability to liberate cities you receive in peace deals. Overall, Civ5 diplomacy made more sense than this. They hate you, you get poor offers. They're neutral to you, you get neutral offers. You're friends, they might hook you up with a good deal, but nothing silly.
