The most memorable adventure game I've played in recent years. The puzzle design is fantastic, the story is fantastic, the gameplay is fantastic. Once you start, you'll have trouble doing anything else until you uncover all the secrets of the solar system.

14 MONTHS LATER UPDATE: Outer Wilds still regularly occupies my thoughts. I, like many others, am eagerly waiting for the day that I've forgotten enough that I can re-experience it from the beginning.
