Setting aside the dollar savings, I find that this is the most interesting and valuable aspect of Game Pass. I have been trying out games I would not have if I had to buy them individually, which not only pushes me out of my comfort zone, but allows me to be free to move on from a game much soonet, instead of wasting time to “find the fun” just because I bought it.
I can also see how this ease of going in blind should help with spoiler-fragile games.
