I think this game is coming to a crawl. The distances are too far between races to allow rapid movement of ships.
If we host 3x (or even 4x) a week then things would happen faster.
Remember, this game is allready on 148 turns which is quite an achievement but it people may start to get bored if it doesn't end.
Besides this is a "Last man standing gets it all" game, so only one must remain at the end....
