Actually, I've played around with random map creation, the results were quite "humble". I'm not a big fan of that feature, because getting to a random generator, almost as good as stardock's ingame one, would take a big amount of time, if a lightning does't strike me instantly, delivering a good and easy solution for that
Secondly, correct me if I'm wrong, I read somewhere, the gameengine is limited to 18x18 sectors, hence no map greater than gigantic will be available.
I think making a map should take you a bit of time, then you will really enjoy your work, but if the majority ask strongly for that, I might implement one. However, I think with the starsystemeditor there is an option available to rather quickly create a map.
I only whished, one could save a random generated map ingame
