Outer wilds is not a 30-hour game. Ive replayed it many times. It is full of interesting, replayable, content.
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.
