The abilities for players to either self-host or rent (like Minecraft realms) a dedicated server/VPS. Just having a daemon service or executable available to upload to IAAS servers like Paperspace or Vultr would be super useful, and I can imagine it would be pretty easy to develop without creating internal infrastructure/ having to collect payment for that extra resource elasticity.
While I can agree it would be nice not having to depend on the “Save Owner” to be available to play, however…
Subnautica being what it is, it is highly detramental to every player who is not available when you are to potentially come back to an abbandoned base, or having a goal in mind to progress the story only to find that other players have already progressed ahead of them.
The game’s progression is heavily based on the story, and all players playing on the same save should ideally be experiencing everything together.
