There's bunch of earth maps (full and partial maps) on my hard disk waiting for conversion from BtS to RoM. I'll convert them from time to time and upload here. The first maps are gigantic Carter's Earth map, one with 32 preset civs and one with random civs. I think these earth maps are larger than Genghis Khan's Giant Earth Map (GEM) so make sure you got high end computer for these maps. Spoiler : Unzip the maps to 'Rise of Mankind\Privatemaps' folder.
