The Cradle of Civilization Map Pack: Mesopotamia includes a single-player map based on the Fertile Crescent region. It covers the Nile River valley to the west and extends east along the Tigris and Euphrates river valleys to the Persian Gulf. The map reflects the historical geography of this area. Players can use random leaders or select leaders relevant to the region’s history. The map is also accessible in the World Builder tool for creating custom scenarios.
