I recently played/finished Subnautica. Brilliant game of of base building, storyline, not a button mashing shooter, looks beautiful, not triple A game, made with a lot of love.
Anyone know/play anything similar because I am playing Fallout at the moment and although the game world is beautiful and complex its basically an action game where you shoot lots of monsters.
Different, but I'd recommend Outer Wilds. Not a base building game, but an absolutely fascinating, and beautiful, planetary exploration game with a real cool time reset mechanic.
