@Imperious-Leader Maybe you went this way since the original design does archetypally the same, but how about, in the land-to-land borders, colourizing the borders of the borders, while leaving the inside of the borders light grey?
This way, you could properly define the colours for the borders between territories with different ownerships (for example, having the border between Poland and East Poland grey on the west and red on the east).
The Soviet symbol in the turn order is different from the ones inside the territories.
The Azores are sometimes neutral and sometimes American (also probably it would make more sense as British than Americans, but debatable and pointless).
In the “AA50 Suplreme Edition” there are no territories for Azores and Malta, but only the roundels?
Also ignoring China and letting them liberate Kiangsu or Manchuria will negate a Japanese National Objective. It takes almost no effort of Japan’s part to eliminate China. Manchuria and Kiangsu are also great for Japanese ICs. They are on the mainland so they do not require a navy to service them. They also can only be liberated by the Allies, never captured. This means should you loose them, they can not be used to produce units that will be used against you.
Also consider that Chinese infantry are “free” any other Allied unit in that area had to be bought and brought there. Which is a bit easier said than done. I see no reason not to stomp China flat from the get go.
