More good news for the modders out there with their eyes set on the world scale, Civilization IV is now supported by Desura. Which means developers will be able to upload and make available their works to the community surrounding Desura. Let's welcome Civilization IV and the flagship mods to Desura!
We are always looking for more fantastic mods to support over the service, if you know of a mod or are apart of a mod that you think needs to be on Desura let us know firstname.lastname@example.org and we will do our best to get it ready, even if we do not support the game the mod is currently for let us know either way.
A larger amount of mods for Civilization IV is currently supported.
To list them all, some prominent total conversion mods such as Planetfall (a take on creating an Sid Meier's Alpha Centauri's sequel), Dune Wars and Rise from Erebus, as well as smaller ones (Hundred Years' War) and those striving to create a feel of "unofficial expansion packs" - Legends of Revolution, Rise of Mankind: A New Dawn, The Ancient Mediterranean and Thomas' War.
