Although civilization blossomed later in the western hemisphere, the region from Peru in the south to Mexico in the north was just as important as an incubator for the development of ancient cultures. This map spans this rugged area of jungles and highlands. The Cradle of Civilization map packs are Firaxis-designed maps of real-world locations. You can play random leaders in these settings, or choose leaders appropriate to the history of these areas. The maps can also be opened up in World Builder, where you can even create specific scenarios.
