On 1914 the borders of Poland and Bulgaria are incorrect, partly because they obviously based the map on Diplomacy rather than a real map of Europe in 1914.
Moscow being placed in Siberia is another howler from many of the earlier versions; though acceptable for some for game balance reasons. Personally I prefer to play on a map that looks something like the real world, though shrinking and expanding some areas is always needed - the curve of the earth means there is no definitive flat world map in any case. But China on the A&A global board does not bear any close comparison with a real map.
The Suez mistake was corrected for the 1914 game. But it’s amazing how many amateur map makers treat official A&A as gospel and repeat the same mistakes rather than researching their own history. Just where is Rio de Oro again? When did Brazil declare war?
I’ve even seen some purported WWII maps include such territories as Bangladesh & Pakistan! FYI New Delhi replaced Calcutta as the capital of British India in 1911.
Another thing I dislike is the Gibraltar territory. For the sake of having this in the game as a vital port a ridiculously large “bite” is usually taken out of Spain. I prefer that Gib is considered as a “Treaty Port”; that is the UK/Allies have use of Gibraltar as a port but it is considered part of neutral Spain. In order to attack Gibraltar the Axis have to conquer Spain itself in which case the port becomes Axis controlled as part of that tt.
Japan attacking Moscow from the east is the single thing that does most to kill the feel of A&A being a WWII game - it sets events in an alternative reality in which Japan risked war with America without securing their backdoor with a Soviet non-aggression pact, and in which Stalin would get involved in fighting Japan before the German war was won. If you want a Pacific war, and Russia having a chance of surviving, then some form of Russo-Japanese pact is a must.
