In increasing order of casualness I recommend: Elite Dangerous->X3/X4->Everspace/Everspace 2-> No Man’s Sky.
Everspace 2 is a spiritual successor to Freelancer, so probably your best bet ( Everspace 1 is more roguelike, but holds up nicely ). Speaking of Freelancer, I hear the game is still alive and has a vibrant community around it.
If you ever want to revisit Elite shoot me a message, I may help you with starting up. They say Elite doesn’t have a learning curve but a cliff, so help is usually needed. Luckily the game has the most welcoming and helpful community I’ve seen in/around a video game.
Other than these, there’s Chorus, but I haven’t played that one and it seems more story driven than open-ended.
Imagine the downfall of framework being the donations made to some obscure (tankie?) dev that a part of the community does not agree with. This toxic “holier than thou” attitude of the linux community leads to fragmentation and will be the doom of the linux phone project too, I swear. Someone will find an obscure package developed by an asshole/tankie/nazi/whatever and will rage about how the project is now immoral because the project devs support it and insist on a public boycott. Why do some people seem to be unable to separate the software from the developer? Framework or the software dev is not your friend. Is their hardware/software decent and open? Cool, then keep using it, tankie devs be damned, or at least fork it and make your own morally pure version. But this endless bickering over what devs support will lead to nothing good.
