In Outer Wilds you are stuck in a time loop and have to restart every 22 minutes, and you're tasked with exploring a solar system. It's really hard to talk about this one without spoiling it, but I'll try to keep it vague. This game is a masterpiece at creating emergent narrative for the player. Each of the planets you explore works in its own way, and it's up to you to figure out how to explore the solar system. It's like one giant puzzle to solve, figuring out how everything interacts and how things change over time. The whole system is so perfectly designed, you could start anywhere, and you'll discover clues to other things somewhere else, and everything just fits together really well. You start the game with everything you need to finish it, and could conceivably finish it in 22 minutes. But for most people it will take around 20 hours, because you need to venture out into the system to gain the knowledge you need to get to the ending. It's just really cool that the only thing you gain through all your journeying in this game isn't some special tool you need to advance, it's just knowledge, learning how everything works, that lets you get closer and closer to your goal. And that ending is definitely worth getting to.
