This is basically what Star Citizen hopes to be, but done right.
Simple but well done.
More plausible end game content and more easing into control schemes (outside of tutorials) and this would be ready to be a AAA+ game on Steam or GOG. Its already Factorio good, it just wouldn't sit well in those markets as a "unfinished product" label since consumers in those markets expect weekly, monthly at most updates, instead of yearly like Starsector is.
