Sid Meier's ''Civilization IV'' also released some bonus content, mainly to show [[Mod (video gaming)|modding capabilities]]:
* Earth – This is the world map of the game, based on the [[Robinson projection]] of the Earth in order to optimize its size. 124x68 tiles large, it features just 9 ancient civilizations.<ref name="rhye-earth">{{cite web |url=http://rhye.civfanatics.net/pages/civ4-Earth-description.php |title=Sid Meier's Civilization Mods by Rhye – Civilization IV official Earth map, based on Robinson projection |author=Rhye |publisher=Rhye's Mods for Civilization |format=PHP |access-date=24 October 2009 |url-status=live |archive-url=https://web.archive.org/web/20091126182754/http://rhye.civfanatics.net/pages/civ4-Earth-description.php |archive-date=26 November 2009 }}</ref>  An 18 civilizations version of this mod was later released which won the first prize at a GameFlood modding contest.<ref name="gameflood">{{cite web |url=http://www.gameflood.com/Index.cfm/Mod/Contest/stgAct/ContestLanding |title=$25,000 Mod & Map Contest |website=GameFlood |format=CFM |archive-url=https://web.archive.org/web/20070422101038/http://www.gameflood.com/Index.cfm/Mod/Contest/stgAct/ContestLanding |archive-date=22 April 2007 |url-status=dead |quote=“No question this is the clear #1.

* Greek World – To reenact the classical Mediterranean, a special map was made, based on [[Hecataeus of Miletus|Hecataeus]]' map of the world as it was known by the Greeks. Extra detail was also borrowed from other ancient sources such as Homer, Ptolemy, and Herodotus.<ref name="rhye-greek">{{cite web |url=http://rhye.civfanatics.net/pages/civ4-Greek-World-description.php |title=Sid Meier's Civilization Mods by Rhye – Civilization IV official Greek World scenario |author=Rhye |publisher=Rhye's Mods for Civilization |format=PHP |access-date=24 October 2009 |url-status=live |archive-url=https://web.archive.org/web/20091126162552/http://rhye.civfanatics.net/pages/civ4-Greek-World-description.php |archive-date=26 November 2009 }}</ref>
* [[Rhye's and Fall of Civilization]] – This mod changes much of the core settings of the game as an attempt at maintaining a sense of [[historical realism]] into the game. In order to do this, it introduces other features such as plagues and congresses.<ref name="rhye-fallciv">{{cite web |url=http://rhye.civfanatics.net/pages/civ4-RFC-description.php |title=Sid Meier's Civilization Mods by Rhye – Rhye's and Fall of Civilization |author=Rhye |publisher=Rhye's Mods for Civilization |format=PHP |access-date=23 December 2013 |url-status=live |archive-url=https://web.archive.org/web/20131201143212/http://rhye.civfanatics.net/pages/civ4-RFC-description.php |archive-date=1 December 2013 }}</ref>
* ''Fall from Heaven'' - a total conversion mod that reimagines the game in a dark fantasy setting, built by [[Derek Paxton]]. Its sequel ''Fall from Heaven II'' became the most downloaded mod on CivFanatics.<ref>{{Cite web|title=The story of Fall From Heaven, the greatest Civilization mod ever|url=https://www.pcgamesn.com/civilization-4/mod-fall-from-heaven-rise-of-erebus|access-date=2022-01-22|website=PCGamesN|date=25 September 2020 |language=en-GB}}</ref>
