Go into this game knowing nothing. The little you know, the better your experience will be.

This game is lovingly crafted from every facet. Each planet has purpose, and the various story bits are scattered throughout for you to discover. Each tidbit lets you assemble the story akin to a mystery being solved by using a board with a bunch of red strings connecting pieces of information. The soundtrack follows you in your journey and underscores each location and discovery, encouraging you to find the next bread crumb. It's a bit tough to put down sometimes, but you'll find good places to stick a bookmark in it.
Some parts involve a bit of creative thinking to solve a puzzle, and that can be frustrating. I highly encourage you to stick with it, because the payoff is worth it.
Everything in the solar system is governed by the game's physics simulation too, for that added layer of coolness. It doesn't place you on rails or shoves you into unskippable cutscenes.
The Outer Wilds is yours to explore. Let your curiosity guide you.
