Playing Outer Wilds

Outer Wilds makes a very difficult design problem look easy, that it successfully manages to make the player self-directed explore based almost completely on their own curiosity. It doesn't even tell you what question to ask in order to find the answer in order to quote unquote win the game. That is such an incredible achievement that almost no games have ever managed to do that had any amount of structure. So I'm hoping to learn a lot from Outer Wilds, especially if they do a GDC talk on how to drive player curiosity.
