Precisely! Exactly! Yes!
But no, to the creation of individual maps. Lemme explain:
I like M&B, but I don't want to wait five more years for it. In other words, way too much work for the mods. But if places on the map could have some sort of value that determines the specifics of the random-gen map, then flatlands could randomly create a map that's generally flat, with a tree or two, and grassy. Mountains could be mountains, forests could be flat with lots and lots of trees, etc.
I want.
I also would like to see some deserts, snowy places, seashores, etc.
