It is not a consequence of having too many systems. They aren't correlational. In a RP environment it is pureply down to the founding factions abilities to colonise the systems they find. An in reality 7 times out of 10, they shouldn't be able to do so.
Just looking for consistency in almost every faction. We don't have to pack stations into every last system. The Edge Worlds by their very nature should be barren, yet their stuffed with all kinds of things.
To me a real gem was to find a station waaaaaaaaaay out somewhere in some desolate system where you wouldn't expect to find it on the off chance. Since the mod has become saturated with bases it's just like.... what's the point?
