===Mods===

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.

* Earth Ice Age – This map is set in the world during the last ice age (20,000 years before present), with 11 randomly picked civilizations.<ref name="rhye-iceage">{{cite web |url=http://rhye.civfanatics.net/pages/civ4-Ice-Age-description.php |title=Sid Meier's Civilization Mods by Rhye – Civilization IV official Ice Age Earth map |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/20091129074500/http://rhye.civfanatics.net/pages/civ4-Ice-Age-description.php |archive-date=29 November 2009 }}</ref>
* 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>

===Civilization Anonymous===
The game had a viral marketing campaign, revolving around a fictitious self-help organization known as Civilization Anonymous (shortened to CivAnon), the intention being to satirise how addictive the game was. With the slogan "No More Turns", the premise was the following: "Rumors have begun to circulate that the newest edition of the "One More Turn" franchise is on its way. STAY AWAY from this game at all costs. You will likely be powerless to its extreme addictive properties once exposed".<ref>{{cite web|url=http://www.civanon.org/home.shtml|title=Civilization Anonymous|url-status=live|archive-url=https://web.archive.org/web/20140629224614/http://www.civanon.org/home.shtml|archive-date=2014-06-29}}</ref>  Various characters were created, and their scenarios were included in various trailers showing the "inside [of] a Civanon meeting for [Civilization] addicts,"<ref name="break.com">{{cite web|url=http://www.break.com/video/civilization-5-civanon-trailer-1875762|title=Civilization 5 - Civanon Trailer|work=Break|url-status=live|archive-url=https://web.archive.org/web/20140421063954/http://www.break.com/video/civilization-5-civanon-trailer-1875762|archive-date=2014-04-21}}</ref> the first of which being played during E3 2005 once an hour at the 2K Games booth.<ref>{{cite web|url=https://www.youtube.com/watch?v=nLqW7G8797U|title=Civilization Anonymous|work=YouTube|date=January 2007 |url-status=live|archive-url=https://web.archive.org/web/20140710213710/http://www.youtube.com/watch?v=nLqW7G8797U|archive-date=2014-07-10}}</ref> These "video testimonials of supposedly recovering Civilization addicts"<ref name="books.google.com.au">{{cite book|url=https://books.google.com/books?id=Uuh7mWLB16MC&q=%22civilization+anonymous+campaign&pg=PA52|title=Ctrl-Alt-Play|isbn=9780786470136|last1=Wysocki|first1=Matthew|date=February 2013|publisher=McFarland }}</ref> also featured cameos by Sid Meier. In addition to this, an "official" website was created by 2K Games with extra content. The Civilization Anonymous campaign was brought back for the following game Civilization V. Break described the campaign as "hilarious",<ref name="break.com"/> while Kotaku described it as a "great promotional campaign" that "comes across as terrifyingly realistic".<ref>{{cite web|url=http://kotaku.com/5569527/civilization-addiction-is-as-real-as-this-trailer-suggests|title=Civilization Addiction Is As Real As This Trailer Suggests|author=Luke Plunkett|publisher=Gawker Media|work=Kotaku|date=22 June 2010 |url-status=live|archive-url=https://web.archive.org/web/20140421081928/http://kotaku.com/5569527/civilization-addiction-is-as-real-as-this-trailer-suggests|archive-date=2014-04-21}}</ref> Destructoid shared this view, saying the support group campaign is "a clever marketing tool", but wishing it existed as "we all know there really are people who suffer from one-more-turn-itis".<ref name="destructoid.com">{{cite web|url=http://www.destructoid.com/join-civanon-potentially-win-big-money-big-prizes-182460.phtml|title=Join CivAnon, potentially win big money, big prizes|date=26 August 2010 |url-status=live|archive-url=https://web.archive.org/web/20150102110136/http://www.destructoid.com/join-civanon-potentially-win-big-money-big-prizes-182460.phtml|archive-date=2015-01-02}}</ref> VantureBeat said the campaign was "incredibly clever and funny", adding "what made it so powerful was not the near-flawless execution and fine detail; it was the fact that it could have been real". 'Ctrl-Alt-Play: Essays on Control in Video Gaming' noted the spoof highlighted the series' "hyper-addictive turn-based gameplay".<ref name="books.google.com.au"/> As part of the Civilization V version of the campaign, 2K Games asked Civilization addicts to submit stories via video in order to win $2,500 and a "framed, limited edition Civilization Anonymous poster signed by Firaxis Games".<ref name="destructoid.com"/> The 2010 version was "updated for modern concerns, like the franchise's broader audience and iPhone editions of the game acting as a gateway drug."<ref>{{cite web|url=http://www.gamesetwatch.com/2010/06/relapse_civilization_anonymous.php|title=GameSetWatch Relapse: Civilization Anonymous Returns|url-status=live|archive-url=https://web.archive.org/web/20140421051046/http://www.gamesetwatch.com/2010/06/relapse_civilization_anonymous.php|archive-date=2014-04-21}}</ref>
