How it compares to No Man's Sky (initial release: 2016, last update: late 2021, on its fifth anniversary) is anyone's guess, it's Windows-only and I'm a Mac girl, and even if I had something to play it on I'm not too interested in spending $45 on what is likely to be disaster tourism. (Edit: apparently it is pretty good for people who enjoy pretending to be a long-haul space pilot, so my “disaster tourism” projection was completely wrong. Yay!)
Also this made me curious what Mr. Smart's up to right now and, sigh, the latest article on his blog is him declaring the inevitability of blockchain gaming; he's even repeating the line about how NFTs will let you move stuff between different games.
