I've probably mentioned this before, but one thing that would improve the online multiplayer aspects of this game would be to allow players who have dropped to reconnect and rejoin a game that they've dropped (perhaps because of a mini-dump or a computer crash, etc.). Might it be possible for the game to remember the IP it's connected to and to allow players to rejoin and regain control of their empire?
I've just played a number of games where someone ends up crashing, messing it all up.
