I’ve been playing subnautica since the very beginning (I was, in fact, pretty miffed at the lack of content of their first SEA build) and I have played it extensively (Steam says uh… 180 hours? God damn!). The base building is honestly pretty cool, as is the exploration, but I still have quite a few complaints about the game that are endemic enough to there not being a point to complain about them, but that still make a pretty fine caveat emptor: There are no effective weapons or critter control, which has annoyed a good chunk of players, the AI is a bit erratic at times, the map is entirely handcrafted and static; and although the early game is pretty open the game is ultimately pretty linear, meaning the replayability and wow factor is extremely limited, and I’m honestly not a fan of the game shifting the focus from survival and base building to running away from big huge monsters in the mid to late bit. However, as a play-once-or-twice experience it’s reasonably pleasing and fun, so if you’re going in with the mindset of “I’m buying a 20-30 hour game that takes pleasure in being unpleasant at times”, it is a nice buy. Honestly, if I could unlearn everything I saw during my run with the game and start fresh I would, because I can only think of how tense, scary and majestic the game is for a new player. It’s just a shame it’s such a disposable product.
