In my little tongue in cheek video I did yesterday (it was

) I was kinda pointing out a lot of these same issues.
Quote: "superflatterrain= 2 in the Setup.ini removed the terrain totally if that's of any help ...."
HideTerrain was the technique I used as suggested by Lee in a Steam thread that gave rise to my little bit of fun. Unfortunately the terrain still exists - as I demonstrated

A full skybox kills the visuals no problem when HideTerrain() is used.
As OP says, the biggest limiter to making anything like this is max height. The amount of "flyable space" is almost nil (this has been revised - see further down). Where I reduced gravity and fall rate to simulate space then a puff on the jetpack and I was out of range. I actually had to use some gravity just to get some kind of "retro".
The other critical one is no ability to change gravity or fall rate dynamically so I can't simulate a propulsion set with jets attached to WASD. (This functionality is required to weigh down a player with heavy loads in more terra style games too!)
For mine, if I had unlimited height then I'm good to go with a 1st person space sim. It's in my head even as I speak. I'll add some neat simulated gravity from a "blackhole", asteroids for visual reference etc. and an asteroid hide & seek shoot-em up is on the board. My navmesh is as good as unlimited too. OP populates the store with a fleet of ships and... and.... and....
