Depends on your taste I guess. I don’t play those games because they are there, but because they are « on my list ». I don’t think games like Ori, Hades, Hi-Fi rush, Call of the sea, Persona 5, etc are trash. And when nothing interests me anymore, I just unsubscribe and come back a few months later when there are at least a few interesting games. I agree that I wouldn’t only play on gamepass :).
Well, I am 30+ years old and have no problem to buy games full price. I would have played those games even if they weren’t on the Gamepass. That’s why I said it’s more a question of taste in gaming that explains why you consider such games just « decent ». I think if you try to list your « 9 or 10 out of 10 games », I will have no or little interest in most of them (and that’s fine, no one is wrong here ^^).
My message was more to take advantage of the Gamepass for the games that are worth it, for the time it is worth it. Even if 99% of the games were trash, it would still be worth it to subscribe and play those 1% (and unsubscribe when you are done).
