A large part of the problem is that new players aren't made aware of this, so they'll take off from their selected "home" planet, do whatever activities they want to do, and unless they had landed at a space port\rest stop in their travels, get returned there when they "exit game", leading to their next session starting at their selected "home" and believing that is the only option open to them.
Then there are the people who want thier "home" to be somewhere unique\"special", which leaves them the choice of the 4 starting cities or Grim-Hex, given the space ports and rest stops all have a generic interior feel, with only small changes in the layout or "extras" (Cargo area, refinery, etc.) which have been bolted onto them: They really should at least do something about the space ports orbiting the planets, to bring their interiors to a point somewhere between the current generic station appearance and that of the city of the planet they orbit (if not to match the city's appearance), given these space ports are there to "represent" the planet to visitors whose ships may not be able to male planetfall (loaded Hull C, for example) and need to disembark there and catch a "shuttle" to the surface.
