For me it’s Return of the Obra Dinn. I was blown away by how well this game is done. I blew through it in like 2 days. The way the story plays out is so cool. Afterward I hassled my wife to play it because she loves that murder mystery stuff but she bought it and still hasn’t played it lol.
Anyway highly recommend if you’re into puzzle games.
I tell people to play this game all the time and that it’s the “real” Bioshock 3
