i was just wondering if it was possibly to make maps that werent continuous (sp) in the civ 4 editor in the same way that the conquest maps were in civ 3. I remember people having trouble with civ 3, making huge mountain ranges and stuff to make middle earth maps etc.

Just turn off both X and Y wrapping, I think it can be set from the custom game menu. Otherwise, some map types like oasis are 'flat' worlds.
