I didn't play for a long time (and I probably won't play until June because I have stuff to do) so I don't know if a patch fixed this or not. I always send delegations. Embassy requests were mostly refused though. Sending trade routes? When I play on larger maps sometimes I plain can't reach the other civ. And if that civ declares joint war out of the blue the trade is over. Whenever I go to the trade table for open borders or luxuries or whatever it is, the AI proposes me ridiculous deals I won't accept, probably has to do with how AI is always unfriendly to me A person who's unfriendly or tries to fight others because the person doesn't know others has problems. Not very nice. (or at least by Canadian standards) The only instances where I have seen AI become friendly is when I can act according to their agenda. We've argued about this before and it seems like we're playing completely different games when it comes to diplomacy. I simply didn't have such problem in BNW. Even the aggressive G&K AI didn't act quite like this. When they confronted/backstabbed you it felt a lot more genuine. War weariness.... you probably got even more of that for fighting Gandhi. It would be cool to have a temporary truce mechanic. No war weariness for X turns and rebuild military. Back to battle again!
