I have read a content In autoplay games I have seen AI win a domination victory, more than once actually. Even efficiently so. (When I run autoplay games I use prince/standard settings. There is little point for higher DL on autoplay since they are all AIs and DL affects AI vs Player mostly). It is a little bit strange to see an AI, effectively win a domination victory one time and then in another game see an AI stop a domination attempt even though they where close. Sure, I can't see why the AI stopped, if they are in a dark age, have bad economy or because of happiness can't take more cities and in autoplay games, I see the entire map, the AIs don't. But still it is strange. So if you play a domination only game, you have to play several times in order to have some chance to see an AI even trying to match you and even then humans will always be better when it comes to tactics than any AI (in any game). But I must say if I would have been a player in one of those autoplay games where an AI won a domination victory I don't know if I could have stopped the AI. Perhaps if I started close to the warmongering AI I could have stopped them before they started to snowballing.
