You’re confusing Outer Worlds with Outer Wilds, both confusingly released around the same time.

Outer Wilds is an indie game where exploration and knowledge is the entire point of the game. It unfortunately has zero reply value as once you’ve pieced together the mystery and how to end the game it’s over. I say unfortunately because it’s honestly the best game I’ve ever played and I sometimes wish I could receive just enough blunt force trauma so I could experience it for the first time all over again.

Your description of Outer Wilds is accurate. The game is over once you've figured it out, but I suppose the art remains. Sometimes I want to load the game just to look at the world, just to enjoy the world; nothing to figure out, just look at it, like a painting.
