The idea would be to have a cohesive, accurate map for much of Eurasia, excluding China. That would mean no irritating, unrealistic, endless Siberian campaigns, as Central Asia would have few territories per square inch.
Anyway, I don’t think you can have Europe without the Middle East, and you can’t have the Middle East without the Niger River, Ethiopia, and India (China is mostly cut off, as is Indonesia). So it would stretch from Timbuktu to Iceland to Delhi to Kazakhstan, in the four corners.
If you wanted to, I guess you could add bits of the Americas as well.
Also, why aren’t there more maps that use seas as territories? I love that.
