Stationeers - The Storm Update: Solar Storm & New Suit

It's an amazing game for the engineer brained, finally got the principles of air conditioning through to me playing on Vulcanus and Venus!

That's not a bad description, though Stationeers is even more hardcore than Vintage Story. It's ridiculously complex, to the point you need basic mastery of several different systems just to survive the opening of the game. I'm talking building complete and fully-modeled atmospherics and electrical grids from scratch, with a single block in the wrong configuration being potentially run-ending (I've plugged my oxygen tanks into an improperly set up system and lost my entire air supply more than once). It's incredibly rewarding after you do figure it all out, though.

It's also the one survival game I can think of where a single minor mistake remains crippling even tens of hours into a playthrough. Your only insurance against disaster is whatever redundancy you built into your systems. It truly nails how monumental a task surviving on other planets would be.
