Play the World will also expand your Civilization experience by adding eight new “Great Leaders;” eight new civilizations with specialized units for each; new map features including airfields, outposts and radar towers; two new terrain sets that allow players to customize their maps; additional interface enhancements like unit stacking and auto-bombard; and complete game editor and scenario support, including feudal Japan and World War II unit packs, that will allow players to create scenarios from any time period.
