Outer Wilds—only just started this, haven't quite figured out WTF I'm supposed to be doing.
Elden Ring—not entirely sure how I feel about this one so far. I'm not usually into super-punishing games, and so far this one hasn't clicked for me.
Hades—I feel like this syncs so well with Song of Achilles and Circe, which I both just listened to.
Binding of Isaac—How could I not pick this up again when I got the Steam Deck?
Horizon: Zero Dawn
Vampire Survivors. I just "finished" this, and by that I mean I've got 105/105 things unlocked, and that's probably enough for now, haha. This game might be the best $3 you've ever spent on a game, but at the same time, you might wonder: "why am I playing this?"
