Just did the dlc for outer wilds recently. It was refreshing how it added to the story without detracting from the main game but It was pretty damn scary for me, a person who doesn’t play horror games. I still think it’s worth it. Somewhat odd choice for the dlc when the main game was mainly an archaeological space puzzle but they made it work.
The coolest thing when you start the DLC is that you realize that this whole thing has just been out there the entire time you’ve been playing and you didn’t know it. Then you finally get there and you can play the entire DLC while the rest of the game keeps going without you.
