Civ IV had a very nice mod called Rhye&#x27;s and Fall of Civilization that &quot;simulated history&quot; up to a point until the starting time period of your chosen civilization, and it had &quot;historical forces&quot; (random and scripted events) that destabilized old civs and sometimes caused new ones to appear. It also had &quot;historical victories&quot;, in addition to the usual victory conditions, that were thematic in relation to the chosen player civ (imagine things like (made up, because I no longer remember) &quot;control all of the Mediterranean by X&quot; or &quot;never lose a city to the Mongols while building 6 academies).
