I really love what the devs have put out, but sadly, I feel like my experience has largely been ruined because some missions would stop progressing (like the Expanding the Base mission in trying to hire an armourer). I've searched up and made use of third-party tools, which I enjoyed because I could get a quick fix in other areas, but it's somewhat annoying that I had to resort to this when I have been rather committed to the grind. If I wanted to progress through non-creative game modes more legitimately, I'd have to delete the offending save files and risk experiencing a progression halt at the same mission or in another mission. I would place this as the highest priority for game fixes if it's possible (I understand it can be very difficult to pinpoint and fix bugs), and additionally, to provide cross-platform and maybe dedicated server support. I deliberately bought the GOG version, since I wanted to pay more for games and other content I could definitely keep and use without an account, connection and/or subscription (unlike music and film these days, for instance); I genuinely thank Hello Games for doing this, and wish more single-player capable games could do this too (unlike Cities: Skylines and Ark: Survival Evolved). I dislike the sparse multiplayer experience on my DRM-free copy, but I will not ask for a refund. I could ask for more, like buildings and sets of buildings more complex than local trading posts and observatories, but I should bear in mind that other survival/exploration games either lack them or have them with compromises. For instance, Minecraft, while having villages, lacks interactive humanoid NPCs, while Ark lacks both interactive NPC prebuilt structures and humanoid NPCs. Otherwise and overall, I think the game is a decent experience. I've managed to clock a decent amount of hours and have found myself thinking quite a while about this even outside of play sessions.
