The Team hasn’t dropped out, so much as the empire fell. There were no actions left that Ur could take outside of holding a single fort that wasn’t the capital. At this point, there isn’t even the possibility of a last stand, since the bulk of the army was taken down during the fight for the capital.
So, nothing has changed at all as far as Ur is concerned, whether it is AI or not.
I think @belouski is still playing, but like myself, neither of us has a chance of victory. All we are doing is keeping a thin amount of provinces out of the hands of other players. Nothing more.
So, yeah, I think the term “dropping out” is a bit of a misnomer. There isn’t any more game to play.
