Considering Yahtzee's review style, that's rather solid praise for the game.
And even though the planet is like an oceanographic space Australia, once you have a stasis rifle and a heatblade, things get a lot simpler. If something's going to be a problem, freeze it in place and start stabbing! Round things out with a repair tool, a cured fish or two, a couple of bottles of water, spare batteries and a few first aid kits and you're all set.
It's been quite interesting, seeing Subnautica move from Early Access to it's current state. Seeing things added in, taken out, graphics and gameplay tweaks. On the whole, I've been quite happy with it. My main issue is that I can no longer tuck a single bed off to one side in the Cyclops, and that's really an immersion thing.
