I noticed it was your first post after I answered:
Welcome!
We all love 1940 here, so glad you are playing it.
I’m going to play AAE for the first time soon and i need a little help.
In the manual it says that the USA does not enter the war before 6 months,is that really part of the game?
Why are there circled territories?
Just play regularly with Germany first, then USSR, then Great Britain, then the USA for the whole game. That pattern never changes.
By circled territories do you mean Stalingrad, Leningrad, and Moscow? If so, they are circle shapes because they are cities, however you play them just like the regular territories.
