In the Warzone Diplomacy server, we are trying something a bit new, with a multi-day saga game. Basically what it is is that whenever there is a war, the winners make the treaty, and then start a new game, adding new countries, etc. We have made the game commerce, in order to make it easier for smaller countries to get more powerful. But...we are having trouble transferring cities onto the next game, is there a mod that lets you do that?
