Outer Wilds is a game you can beat in 20 minutes, but you spend 15 hours figuring out how to actually do that. Along the way you unravel a lovely story of curiosity and discovery and loss, while trying to solve one of the greatest mysteries in the universe. It's a beautiful game and a true once-in-a-lifetime experience in the most literal sense, since you can only experience it once. Like the other person said, if this sounds appealing to you, give it a try! You will absolutely know whether the game is for you well within the refund period.
Good luck, and remember: always read the manual!
