I downloaded this, it looks fun and interesting, however so much is wrong with the geography. If one is to take Earth maps seriously, the geography has to be correct. Otherwise one may as well play Terra or Fractal.
Just a few things within a minute or two or loading it up:
Nairobi should be 1SW - tallest mountain in Kenya is north of Nairobi.
Seattle - check out the latitude, it is N of Montreal. The spot 1S of your Seattle is Vancouver.
Likewise, San Francisco much further south.
Caracas - no way is that spot Caracas, should be 2W.
Belo Horizonte - again no way - shd be 2E.
Kampala - shd be 1E right on top of lake Victoria, there is no meaningful city in the game spot.
N'Djamena - this is the most obviously wrong name/placement - N'Djamena is south of Lake Chad [2S 1W of your city]. If you like the city you have, if should be called Mao.
I could probably go on if I looked at the entire map.
So sorry to be a bore but I cannot play an Earth scenario which has so many geographic errors :/
However I am sure it is lots of fun if one does not care about such details
I strongly recommend google maps to get these things right o7
btw as excellent as Rhye's map is, there are a few improvements that can be made to reflect real geography - my map makes a few changes:
