You will control your vassals loosely. They will not be able to play a part unless they are controlled by someone, so I'd encourage you to get a friend to become one (maybe the Mycenaean Colonies) so that you can reap the benefits of owning a vassal. However, since it has no player controlling it, it will not play any part in the game, so you can just ignore them and launch attacks on your closest player, the Hittites under Emperor Potato_Guy. Right now I am working on two things. A way to get a sort of Tech System and Trade, and a system so that you can fight non-player controlled civilizations.
