I’ve played one through twice (Wasteland 3), A Plague Tale: Innocence which I’ve never finished because it makes me ill to play it too long, and Humankind which I intend on playing more of but am distracted by playing WotR right now.
That’s it.
But, at full price at release, WL3 and HK costs would be what I’ve paid for the service to date. As long as I play a couple new release games a year, it’s paid for, and it gives me the chance to play games that I may otherwise never finish or play if I owned them. Many of the games on the service I already owned elsewhere when I joined, so there potentially could have been many more.
So, as long as that trend continues, I’m fine with it. I watch the cost/benefits ratio pretty well for anything I do, so once it starts failing, it’ll be gone (much like how I dropped Humble).
