The idea, at least for the initial version, was just a standard Earth map (probably based on YNAEMP) of whatever size is convenient. The difference would only come down to resource placement; besides adding a number of deposits of Omnicytes, Dilithium, and Neutronium, I'd also tweak the deposit sizes and numbers a bit for the other resources (especially Oil, Aluminum and Uranium) to better match my revised spawn tables. It's just that a lot of people like using Earth maps, and the ones with pre-set resource distributions don't work with this mod thanks to the resources I've added and changed. I've got lore-specific justifications for where these new deposits would be placed (I posted a list somewhere in the old thread, but I'd have to search for it, keyword "Antarctica"), but it's pretty flexible. I'm sure it's not too difficult to learn, but my plate has just been really, really full with the Mythology rollout/debugging and integration of Ascension into the 4-mod design. So I keep putting it off. Now, there was also talk of a scenario map for games starting in the Digital, for a SMAC-like experience, and THAT one could have plenty of fallout, spore towers, etc. pre-placed. But who knows when I'd get to that one.
