Subnautica minus: - The deep story - Twists and turns - Horror/dread - Graphical polish - No real scary critters Build systems are more like Astroneer, very simple and very obvious. Environment reminds me of Satisfactory, in that is it vast and hand-crafted. The first impressions of the gameplay are not impressive. The first 30 minutes had me going, "Oh no." Then why rate this 5 stars? The build systems are rewarding and deep without being Space Engineers or Kerbal. You'll enjoy this if base-building and sim management are your things. I particuarily like this because I love games where you "fix" or "regrow" or "heal" as part of the main mechanics and theme.
