Made me laugh....
Super Cruise is fine
Ships dog fighting in space like there's an atmosphere and gravity is fine
All kinds of fantastical weapons and ships of so many shapes (why are empire ships more aerodynamic than the rest? does it matter in space?)
Fuel scooping, I'm sure that is 100% possible with a few odds and ends from the back of my kitchen drawer, the one with the old batteries and keys for things I've long lost...
However there is a simple reason for having the opening facing the planet....it's where the people who built it live (well in the game of course, which you may have to suspend belief in order to swallow that one too). Why have shuttles flying round to the other side?
And also.... try flying round the space station in super cruise and point to the station with the planet behind you and guess what....you face the entrance....
Why not have a second entrance - well I do have to question where you'd put that big spike at the end? You really need to think about these things! ;-)
Lastly there is of course outposts if you don't want to land in a spinney thing
Although I am hoping this was just a hand grenade post....post it and let it explode rather than some lack of understanding of games/fiction
Live long and prosper a wise alien once said, he was real too!
