It's amazing how fun this game is and its not even finished. Though not complete, it seems every week there is a new tweak, polish, expansion or something completely new added to the world and story. When I went through the existing game back in early February of this year, I was entertained for hours and hours. I would guess that was about 1/3 of what it is now. It's almost unbelievable how much it has grown in the last six months. Subnautica Below Zero is still in development, but like I said it's playable and a lot of fun right now.
