The greatest game I have played to date - a diverse, fully-realized and immaculately rendered solar system that can be explored to solve a non-linear mystery that involves mastering time management and manipulating the physics of your environment. Beautiful design and moving meta-story with an ending that conveys better than most works of art I've ever encountered the importance of understanding that some things cannot be saved, and more potently, that doesn't have to be tragic. Whatever you do, play this game, and don't read a single thing about it. You will not regret it.
