You should download the new version of the rules in the files section here. There will be some differences from the print n play version, but there are a few clarifications.
Yep, saw the new version and downloaded it, thanks for posting.
Because the game is straight-forward, players can just have a fun hex and counter brawl. But also I'm sure some neat variants could be introduced. How about Germany's Z fleet or a range 6 bomber fleet? Of course the German player should have to trade some forces in to keep the game balanced. Hmmm...
