Interestingly, my first thought was Resident Evil 2. I didn't love it, but it's really stuck with me. Abby's playthrough was a great way to revisit the game without having to play through it myself a third time.
When I think about it though, Apex Legends is definitely my favorite so far. It feels so fresh and exciting to play, and I can't say I felt the same about PUBG, Fortnite, or Blackout. I've slowed down on it a bit but I can't deny how much of a surprise it's been. I love stealth launches!
