I have found 2 changes to the map that enhance the game play - thought I would share.
Darfur - Minor Aligned with Ottoman Empire (1) IPC. This new territory sits between French Equatorial Africa and Anglo-Egyptian Sudan, with Belgian Congo keeping a border on AES. This change provides more action in Africa, without it just becoming a big waste of space by turn 3 or 4 and an IPC pump for the British.
Sea zone 31 - A new sea zone that splits SZ17 in half. SZ31 borders SZ16 to the west, SZ17 to north, SZ19 to the east, and Libya/Egypt to the south. All of Greece borders the new SZ31 and SZ20. This change provides much more freedom of movement of any CP ships that leave their home ports from mine rolls. From the Allied powers standpoint - protects from an AH early thrust into the Black Sea or Eastern Med.
