My first thought, of course, is the foundry, but perhaps that's only for maps in progress.
I bring this up because I have some serious critique for the WWII Western Front map.
For starters, Bob is inaccurate in terms of where you can attack. Maybe this is a Bob issue rather than a map issue, but there are a number of one way attacks on that map and Bob leads you to believe that you can attack the "other way" on them.
The biggest issue, however, is the restricted nature of the map. The mountains create a situation where Western Germany can be guarded by only one defense. Should you be fortunate enough to get Britain, you can guard both areas from one spot as well. Further, not only can you guard either from one spot, that spot can only be attacked from one spot. This makes it nearly impossible for the other players to gang up on a player if he is able to secure either of these areas. Meanwhile, it's pretty much open season on France from any number of spots and even Northern Italy needs to be guarded by two areas.
I do not say this because of sour grapes, I won my only game on that map by exploiting the very vantage point I mention above. And I did so without getting a ton of armies in Germany to begin with. By the end of the game, everyone, including me, realized that, more than anything else, I simply benefited from a sketchy map layout. Had the guy who initially took Germany withstood my first attack (I was the only player in position to hit him BTW), he, rather than I would have likely cleaned up. However, good dice on one turn and one turn only made my victory inevitable.
It would seem logical to, at very least, connect Italy and Western Germany or perhaps make the mountains more passable from more areas.
