If any of you are interested in online Fortress America play, we have a yahoo group, a ranking ladder, and an on-line version of the game (with a few minor mods to facilitate on-line play).
Yahoo group:
fapagroup : Fortress America Players Association

Given your comments above, I think that some of you may learn some new tactical lessons by playing a broader set of opponents. Bombers in detroit or Minneapolis doesn't sound right & USA always losing in 2 player games doesn't sound right (although its about 55-45 in the invaders favor in our experience).
For official "ladder matches" leading to rankings, we use a 2-out-of-3 method to balance play rather than changing the game itself. Sides for the third game are based o how well each of the first 2 games were won.
This is a great group that avoids the flame wars so common in other gaming groups, so if you do sign up, please keep it that way.
