Only the "World" mapscript (by
@Toffer90) is still maintained and you can be sure that all current resources are included so that is what I usually use. It would have been great to have a script that includes space but the modders have said, that they want to put all effort into multimaps instead. Therefore I have created a bunch of space scenarios to bridge the time until multimaps can be used.
All my space maps are based on the "World" mapscript. Do you miss a certain combination of settings in my space maps? I could make a new spacemap from your suggestions. I am only restricted with the size of the earth part of the space maps: I can only do 60x40 ("duel") or 108x72 tiles ("large").
More information on my space maps can be found
here.
