No. BlueMarble should work with all CD/DVD-versions of Civ4, Warlords and BtS. More info you find on the homepage:Does thet need Bts?
Sorry, the mod exe installer only works for the PC version, as I do not have a Mac. AlanH found and supports a way to make it available for Mac:I downloaded it. But which folder should I put it in ? Also I have a mac so I don't know...
Hey if I'm playing a mod like fall from heaven can I still use this or would things be incompatabile
Sorry, the mod exe installer only works for the PC version, as I do not have a Mac. AlanH found and supports a way to make it available for Mac:Is 3.0 supported on OSX?
