Yes; there is no "connection info" dialog in the bottom-right corner of the connection screen before the game starts to show me that all the other players are AIs--I guess there wouldn't have to be, since they are all already connected. . . by not existing in the first place!
Very annoying; without the warning that the game will be 100% AI, I don't have the chance to quit it. Why the hell does the game think I would EVER want a 100% AI game without at least TRYING to put a real player in place?
If I was okay with bot games, I'd go play the single player =/ At least I could edit the game files to give myself favor pts there
