What I find unique is the scale of these maps and perhaps planets and asteroid belts around them combined with extra zoom out distance.

I hope that the things that make these maps unique can be reverse engineered and reapplied in fitting ways as well as hopefully having Planetary industries, space bases and gigantic resource operations.

With maps of this size the capitalship slow acceleration but high max speeds of the mod "Path to Victory" work well here. Personally I managed to do an overrideBigfile command combining this with Path to Victory 0.04.
