I noticed it was your first post after I answered:
Welcome!
We all love 1940 here, so glad you are playing it.
What about the AAE board would you change for AAE Historical Edition? I would suggest Libya and Egypt split in 2. Bessarbia needs to be changed so that it connects to the Black Sea. Germany also split in 2. Either Med. needs to be less spaces or the atlantic needs to be bigger. Perhaps Belorussia and Ukraine needs to be split in 2 as well. Also the US should be recolored to revised green and not the blue. Why is it blue anyway? The UK recolored to revised tan. Germany recolored to revised black or dark grey. Italy becomes a separate power colored light grey. This includes Libya and possible adding Albania to the board.
No problem with accurate IPC, and setup.
Balance is easily solved by victory condition and game rules.
