Elden Ring.
My guest attempt at a Souls game was Bloodborne as part of the PS+ PS5 selection of free games. I'd heard so much about how great the game was, attempting playing Bloodborne for about 30 minutes and then gave up.
Then, a little later I decided to try Demon's Souls Remake. I played it for about 25 hours, but ultimately gave up. I did enjoy it a bit more than my attempt at Bloodborne, but I didn't yet understand how to really play these games, so it wasn't an experience that I really liked all that much.
Then the hype surrounding Elden Ring got me. What people were saying about the open world got me to give the genre another chance. I was determined to get these games. And after about 20 hours with Elden Ring, it just clicked. I figured out what made them fun for me, and I haven't looked back. I love the genre (playing Mortal Shell 2 right now).
