If it wasn't for Game Pass, I would have never discovered some of my favorite games (Yakuza, Dead Space, Spiderheck, Vampire Survivors), but you need to remember that you're still paying for it via Doritos and/or Pringles. And even then, it expires and you can't play those games anymore.
Once my subscription ended, I just bought all those games either with MS Rewards or on used physical disks.
