My partner has a ps4 and some subscription thing (PS now?). It ends up being about 6$/month and new games are available each month (including some AAA). If each month you add them to your library you quickly end up with a backlog of more games than you can play.
games seems to loose value rapidly after they are released so some are very affordable.
I just can't get over the idea that a game I'm playing today might be removed from gamepass tomorrow. As a result, I don't want to play anything on gamepass, or subscribe. Although I think I might have somehow accidentally subscribed anyway. I'll stick to gold.
If it get pulled and you enjoy it that much take advantage of the discount (every game on Game Pass has a somewhat discounted price for members) and buy it. There’s been a handful of games here or there I didn’t want to lose when they were retiring, and others that I played but didn’t really miss. I still save a lot of money compared to buying every game I ever want to play - especially given many of them I enjoy but not enough to shell out full price on
(Also xbox sales are often very good. I'm ok paying $10-20 (sometimes less!) for games).
I suppose it helps that my backlog is 6 years now; up until last week I was still playing games on 360/ps3.
