This game has been available for about 9 months, I waited to play for 6 and another 3 months until posting this. If the final game is as fun as the initial Subnautica game when complete, I will be happy. As of 10/2019 however things could be better. All voice-over tracks are disabled by the game at this time. Subtitles are an option for those willing to go that route. The current game I quit didn't have enough lithium. Almost none. So I enabled console, cheated in scanner rooms and verified where it SHOULD have been. Previous partial playthrough did have enough lithium for 15 hours play or so... I'll give a positive review. If game updates stagnate, review will be updated to show NOT recommended.
I trust in the Subnautica team will be finishing their game and likely it will be great. Sadly, many well-known AAA game corporations in general .. increasingly true... have been making terrible sequential titles.. as in they get worse.. much worse. I don't believe the Subnautica series will do this to us but I have to admit right now being slightly bummed about the state of things... Gorgeous and problems..... :)

1. The Unstable Build has voice-overs enabled.
2. When I just now tried this Beta Branch version, I had less trouble finding Lithium. Maybe a bad random game in Stable Branch or maybe they have changed the unstable resource distribution.
Those were my to specific complaints for the Stable Branch (default) game version as of Oct. 07, 2019. So that was a relief to discover. I also did not encounter any more bugs or game-breaking problems using the Beta Branch. Also good.
