Please stop removing war after someone resigns in Age 3 (4 players). Just replace them with a bot or do something else. People resign in the case of war and ruin the game. This doesn't make any sense. It shouldn't work like this.
You're playing a military setup in Age 3, building units for 4 turns, while other people are just farming culture. If you declare war on someone, they just resign on purpose (trolling, because they're not going to win anyway), and you get nothing, giving a straight win to the other 2 players.
I'm not even talking about the AI resigning; it's the ultimate level of trolling. I'm playing a 2-hour game, just for someone to leave and the AI that replaces him just resigns.
PLEASE VOTE FOR THIS TOPIC! DEVS, PLEASE FIX THIS!
