Outer Wilds is a gem of a 3D first-person indie game. Other games might have you find required items so you can progress (like Pokemon or Zelda games), but in this game it’s all about the knowledge you learn while playing (like Tunic). You explore, learn, and puzzle solve. By looking up anything about the game, or by looking up a solution to a puzzle, you essentially lock yourself out of experiencing that piece of content. It’s all about the journey.
It’s a game you can only really play once, but it is so worth it. It’s my favorite video game and I wish I could forget everything about it so I can play it again for the first time.
My partner and I played through Divinity Original Sin 2 many times with co-op, and now we are playing through BG3 and we are having the time of our lives. It’s really really good. It’s like co-op in DoS2 but I’d say it’s even better.
Just make sure you recruit someone and they recruit someone to your party (just like in DoS2) so you both get to control another character. But it’s really easy to switch out party members if they are in your camp.
