I can't speak for other games, but nothing has been laid down yet for SGN. My initial thoughts are to design 6 game maps, 3 British and 3 French. Work up some type of scenario for each of those mats (cutting out, blockade, fortress assault, etc.). Then give each commodore a set number of SOLs and frigates and have them assign them to each of those missions in secret. Then just play those missions with what each player assigned to it. You might need to assign an order to the missions before you start and limit how much resources can be allocated to each of them. This still needs some flushing out, just thinking out loud here really.
