I’ve often made that comparison myself, though I hesitate sharing it in order to avoid triggering a possible knee-jerk response.
Outer Wilds is my favorite game of all time :) It is generally quite chill (though there are a few tense moments). I hear the DLC is a little scary/thrilling but I haven’t played it yet.
For anyone who likes this style of game, I can't recommend Myst and Riven enough.
Haven't gotten around to the later games in that series yet.
I should note I haven't played Obra Dinn, or Outer Wilds yet, so I may have misunderstood.
