 The original game was removed from the iOS App Store on September 1, 2016.The main game of "Civilization Revolution" begins in 4000 BC, with a lone settler unit in the middle of a little-explored region.That settler has the capability to found a city, which, depending on its specific mix of geographical surroundings, begins harvesting food (for the continued growth of the city), production (for the creation of units and buildings), and trade (that can be then turned into either research points or wealth).
