You mean activate autopilot and the AI takes over for the rest of the game, without needing to run+commit every turn?
Sadly, this isn't possible (would make my wunderwaffe ladder run a lot less boring; watching the bot mess up the expansion wasn't cool).
Definetely a good option would be to set a turns counter for using the bot. Say, you set it to 5 turns, and the designed bots plays it for 5 turns without needing your input. Doesn't sound too hard to code.
Do drop it on Uservoice; it's a great suggestion. All about whether or not Fizzer will actually put it.
(EDIT):
take into consideration that if your opponent want to play against AI he can just go to single player ;)
Yeah, but say, you're playing an alhazi-tier player who is on their last legs but won't surrender. You have to commit every damn turn when you can just wunderwaffe your way to victory.
Also good for large FFAs where you are dying, but surrender is set to requiring accepts; at that point, I don't bother thinking anymore, I just drop in the autopilot every turn & call it a day. Would be one less game to worry about.
