Rhyes and Fall of Civilization

Description
Like the name suggests, the central theme to Rhye’s and Fall of Civilization is the simulation of historical
civilizations’ roller coaster ride of power shifts. Although Civilization 4 is generally set up so that civs
simply grow more powerful over time (unless conquered), RFC has a new mechanism that allows
civilizations to collapse into barbarian cities, and even rebirth from uncivilized ruins or foreign domination,
given the right circumstances.
This means that in one game multiple civilizations can fail before they all even spawn, and in another every
single civilization can survive through the entire game. Thus in a given game, both China and Rome can
succumb to outside invasion and cease to be civilizations at all (possibly coming back later), or they may
survive and thrive into the late game. Triggering these breakdowns can be a key strategy for human players,
since only AI civs can collapse.
