I've played subnautica, think I have about 2 days real time logged. It is a bit collecting stuff to get to the next item so you can then go further. However, I think the environment and the story are so well done, it's not like other games like that.
It's more survival horror, than collection and base building. That area of the game is pretty robust though. I really enjoyed finding out more about the strange planet you've crash landed on.
It's nothing like Left 4 Dead or Half Life or anything like that though. I would liken it more to The Long Dark but set underwater (and better). I would really recommend it.
