In terms of farming, floodplain farms are a new feature built near the Nile River. A further addition is the use of Irrigation Ditches to increase the fertility of farmland. Fishers operate in boats, usually situated in the Nile. Hunting is a new feature in "Pharaoh"; animals to be hunted are present on the game map. A wide variety of raw materials and manufactured goods are available in "Pharaoh". Materials include clay, which is manufactured into pottery; reeds, which are manufactured into papyrus; and various types of stone. Both raw materials and goods can be traded with other cities in exchange for currency. On some city maps, the raw materials necessary to produce certain goods are unavailable, so importing sometimes expensive materials is necessary. Exports are often necessary to produce money for city finances.
