First thing I have to say is "really good" is quite the stretch. Making a space game without aliens, when all the major events have already happened, when all major factions are at peace, that set up couldn't be saved no matter what. It was guaranteed to suck.
Second, I agree about the technical limitations. That's not just creation engine being held together with duct tape and chewing gum with vibe coded additions bolted onto the side, it's a universal one.
The tech just isn't there for a good open world space RPG. Space is so vast that it by necessity ends up procedurally generated and thus forgettable and repetitive (Elite Dangerous, Starfield, No Man's Sky)
The closest we probably have to what people want out of a space game is Star Citizen, where it's handmade locations in procedurally assisted planets. But that games taken in a billion dollars over a decade with no release date in sight, and for all the tech theyve built it still isn't enough.
