I cannot recommend Outer Wilds enough. It is a game-defining game. There's a little caution in the recommendation: some people complain a bit about the controls (they're a bit realistic and therefore unforgiving), and it's playable with keyboard and mouse but a controller makes things a lot easier. A lot of the value in this game comes from discovering things for yourself, and it is easy to get spoiled. If an exploration game (in the true sense of the term--not the "we have a big world and will send you on pointless fetch quests" you see often) where the only inventory you have is your own knowledge sounds anywhere near interesting to you, you should play and also not spoil yourself with reviews that might tell you critical concepts that are best to discover yourself.
