I'm trying to create a larger scale version of the "Gifts of the Nile" map. I loved the scenario version, but it ends at turn 125 and I wanted to make it include territories farther south along the Nile and have a larger delta region. However, I know the scenario has special worldbuilding tiles, such as the cataracts, which can't be produced in the regular worldbuilder. Do you know if it's possible to create a new map with cataract tiles? Would I have to dig in the files, or could I import it? Also, very general question, when creating a worldbuilder map packaged as a map mod, does it matter what mods are enabled before creating the new worldbuilder map? How do I create a map that I can play on with any mods I choose?
