What you can do is impressive. I'm not going into a detailed depiction, but people who've played the SC persistent universe know what I mean. It's somewhat mind blowing in scope. It's also heartbreaking because it's utterly broken in so many ways that no AAA studio that actually needed to sell new copies to new people would ever tolerate. I keep a list of the most egregious/humorous things that have happened to me from spawning in the middle of the sun for no reason, to having my ship blow away on the surface of a planet.
I think there are a lot of possible explanations for this, but I suspect the main ones combine scope creep, constant tech stack changes over a really long dev cycle, and not having to make a playable game to be rewarded financially. I hope some day it becomes playable, because it's really a neat platform, but I sort of doubt it ever will.
