Subnautica has gripped me ever since I bought it. I played it years ago when every few months you had to update your save to see all of the new additions and bug fixes. Editing terrain is something I would like to see it come back in some degree. The overall environment of Subnautica brings a huge fear factor, I did not go near the areas with the Reaper Leviathan until I had the Sea moth Perimeter Defense System (SPDS). Whenever I hear that roar I save and quit instantly. Then have to prepare my self to re log and run for it.

Pros:

- big world
- lots of materials so you wont run out for along time
- great story line to follow and it can get really interesting

Cons:

- alot of grinding can annoy most players
- price increased on steam store
- no auto save, so you better remember to save often

Overall you should buy the game and try it out for your self. You can always refund it if you dont like it. I trust that you wont :)
