The map is really great overall, but there are areas for improvement. There is no Matahorn in Alps or Mount Roraima in Brazil. The Brazilian amazon is all flat rainforest. This makes growing a city with infrastructure VERY DIFFICULT. I could not find any hills. Amazon has no resources capable of being mined (at least I need not find any in ancient classical or medival era. In fact on the real earth there is actually plenty of mining that goes on in the Amazon.
