I must say the map looks very high rez. Do you mind telling us what the final resolution is?

Today I tried to reverse-engineer it. I measured that it is a full screen (almost) from the Eastern edge to Fenris' lair. The "European" part is about 8 times that and the "African" part is about 10 times that. So the landmass without the ocean should be 30,000 px width.

Or it might be the case the my iPad (3) is somehow extrapolating the image so it fills the whole screen. Anyway, it is impressive!
