To clarify:
I mentioned the Milton Bradley edition in response to the post which said “compare AA50 to the first Axis & Allies from the 80’s….same kind of jump from AA50 to AAGlobal…” My point about this was that the board size jump from AA50 to Global should be equated to the board size jump from earlier games (like Revised) to AA50, but probably not to the board size jump from the Milton Bradley edition because the MB edition used a larger board than Revised.
I also mentioned Global, AA50 and AA1942, but my point about those three games was that they are basically three different-sized boards which use a very similar “Google Earth” art style to depict the world.
