I think that’s actually based on one of mine from a long time ago (with some edits, some colors and labels are different than what I made. The original is on my deviantart: https://www.deviantart.com/crazy-boris/art/800-world-map-738565862),
Honestly it’s not that good. I just sort of eyeballed a lot of the borders without really thinking, and I have no idea why Tibet is so huge and is up into Xinjiang, and I know for sure a bunch of countries are probably missing, not least in Mesoamerica where I got lazy with “Maya city states”
It’s honestly a little embarrassing, if someone was gonna steal and edit one of my maps, why couldn’t it be one of my good ones?
I think the edits were done because this Map is now supposed to be for 820 while yours was 800
