When it comes to “games I need to follow until the end or I forget everything and have to start over” that’s when I really focus down the games.
Story heavy games like the Ace Attorney series or Danganronpa are best marathoned so you don’t forget the small details that matter (at least until you clear the chaper). Likewise, puzzle heavy games, specially ones that build on your knowledge like The Witness, Tunic, Return of the Obra Dinn or Chants of Senaar are ones I also focus down so I don’t forget vital info involved in even playing them.
I work a full time job, but I don’t have responsibilities like children, so I have way more free time to play games.
I’m currently playing, Kingdom Hearts 2 and Bug Fables, alongside some friends so we can talk about it together.
With my partner, I’m playing, I was a Teenage Exocolonist, discussing our choices and how our game diverged.
I’m also playing solo: Octopath Traveler 2 and Lies of P.
I’m basically hopping around the various games constantly. I’ll play one chapter of Bug Fables, then hop over to Lies of P and clear an area and defeat the boss, then jump over to Octopath Traveler 2 to clear a chapter or two from some characters.
