Subnautica seems like a whimsical little, "Heehee, I get to swim with the fishies and learn about them," kind of game at first, but it's actually not. Well, there is a little bit of that, but Subnautica features what a lot of survival crafting games lack, and that's story and meaningful progression. You can indeed finish Subnautica. It's a survival crafting STORY game.

You'll be surprised how you'll easily learn what builds into what, and how those things that you build keep opening up new tasks for you to do. Those tasks then bring you to new places which raise or answer more questions about the mysterious environment you're in. The environment is really good. As you surely know, it's underwater, but it's actually a pretty huge, carefully constructed map. At first I was unsure if it was procedurally generated or not, but it's definitely all intentional.

Survival crafting games are nearly synonymous with being incomplete messes unfortunately, but Subnautica is not one of those games. I don't even think survival crafting is a genre that really appeals to me, but I loved Subnautica. I think many genres have that one game of theirs which even if it isn't your usual thing, is still a great game. Subnautica earns that spot as the game you'd think of when someone says, "I don't like survival crafting games, but I still like..."

my fav game 4 ever! we love the cuddle fish!

Waiting for subnautica 2!!!!
10/10 game btw
