Civ5, or its DLCs and expansion, comes with maps featuring... -lots of deserts (Sandstorm) -lots of forests (Arborea, Tundra) -lots of hills/mountains (Highlands) -lots of jungles (Amazon, Rainforest) -lots of islands (Archipelago, Tiny Islands) -lots of lakes (Lakes) -lots of plains (Great Plains) -lots of tundra/snow/ice (Bering Strait, Ice Age, Tilted Axis) ...so the maps have most terrain types covered, but there is at least one glaring exception: swamps/wetlands, or as Civ5 calls them, marshes. I can't pretend civilization is starting in Florida... I don't know how to make map scripts, or I would do this myself, but would someone who knows how mind making a swamp-heavy map, perhaps by simply modifying the Arborea, Amazon, or Rainforest maps so that instead of generating forests or jungles those maps generate marshes? Or point me in the direction of such maps, if they already exist? I'd be grateful, thanks!
