I went to Mexico this summer and had Mexican Coca-Cola. I spent a large portion of that vacation bouncing off of walls like a particle of hydrogen. Any way, I was screwing around with paint.net, and decided to make a generic "Native Americans colonize Old World" map. All borders are hastily and arbitrarily drawn to maximize ethnic conflict. I call it "Reverse Columbus". Thanks to some person on AH.com, who made the base-map for this.
Dark Green: Mexika (Aztec) Empire
Lavender: Maya Empire (See what I did there?)
Yellow: Inka Empire

Absolutely no aspect of this map is supposed to make any plausible sense whatsoever. It is designed to be the only map that can throw someone into conniptions without including the modern Kazakh border.
