This Middle Earth map (56x49) is a custom map I created based on THIS map, which is accurate to the one in the Lord of the Rings books I own.
This map is simply a standard Civilization 5 map and has not been modded. There are 12 Civilizations and 7 City-States, with starting positions where factions in a Middle Earth map should start. Right now I don't plan on making this map into a modded scenario, but I must say that I would love to see a Tolkien-themed mod in the future. If you plan to use my map, I would appreciate it if you credited me.
Comments and criticisms are welcome here and in THIS thread for the map.
