Rhye's and Fall of Civilization (RFC) is a "fan scenario" (mod) for the 2005 computer game Sid Meier's Civilization IV. It is an 'Earth simulator' that uses a variety of scripted events to mirror history much more closely than a typical game of Civilization. The name of the scenario references its core feature—the dynamic "Rise and Fall" of civilizations through time—and its creator, Gabriele Trovato, known as "Rhye" in the forums community.
