I'm worried about the World Congress, even though it's something I want, if the AI is still so insane diplomatically. Backstabbing needs to be changed to be less common. I also don't think the AI should get so mad about certain things, like building wonders they wanted to build or building cities, nor should "friends" ask for gifts constantly without a proposed trade, which basically begs you to harm the relationship when it is really the fault of the requesting civ. Puppeting cities, backstabbing civs, denouncements and lots of declarations of war should bother other civs, but there needs to be more balance before I am so anxious to put the existence of my trade routes and ability to use luxury resources in the hands of the AI players.
