I think this is one of the best computer games ever written.
It is not without its bugs and foibles and can be enormously frustrating at times - that's what the forums are for! But you cannot help but keep coming back to it and back to it, pushing through. It's a puzzle library in a museum in an interdimensional anomaly in a beautiful little pocket universe.
Yes ... it's just so damn beautiful!
And they have given you the most fun spaceship ever to pilot around this place. I presume the experience is still wonderful on PC, but on a games console the tactile loveliness of controlling that little vessel with triggers and sticks is addictive.
And Andrew Prahlow's haunting soundtrack complements the rest of the team's huge, masterful, stylistic achievement.
Watch out for the ending! It packs a serious emotional punch!
Ps. I'm currently playing Echoes Of The Eye, the (so far) only DLC available for Outer Wilds. It is every bit as good as the main story!
