I'm on the same boat, all the way down to my love for returnal. The content drought has persisted for so long that I've fully moved to PC gaming and thoroughly enjoyed myself. Playstation becoming a PC port machine also didn't help their case.Yes, I'm disappointed. Content draught made me finally take the plunge and build a big, beefy gaming PC and honestly my PS5's taken quite a backseat since. I used it mainly as a Final Fantasy XIV machine before, and I've migrated XIV entirely to my PC so it doesn't even do that.
Occasionally I'll play my JRPGs from PS4 on it since I'm still slowly making my way through the big backlog of them that I have (still missing 2 Trails games until I'm officially up to date!), but even then, the only reasons I'm playing them on PS5 are that it's easier to stream them to my frands on Discord, and because I want to have them in box.
I respect all of their studios' work, but the only studio under Sony that is really breathtaking to me is Naughty Dog. Until and unless they release something new and exclusive to the platform I bought, I have to face the reality that I paid 500 bucks to play Final Fantasy VII Rebirth. I'm quite well off so that realization doesn't bother me financially, but I can't imagine a lot of people feel thrilled about that.
But I don't know if there really are a lot of people in my situation. I think players like myself, who became loyal to Sony over their weird, niche Japanese games from the PS2 and PS3 era, are either long gone or have graduated over to Spiderman or whatever. I definitely see the appeal of stuff like Spiderman, and Days Gone, and God of War, and whatever new Marvel thing they'll make after Wolverine, but unfortunately for me, it's stuff that I always try (if nothing else, just to have the experience), and I rarely tend to genuinely love.
EDIT: Except for Returnal. Returnal fucks, and I want more games like it.
The fact that we've gone year after year with horrible third party showcases and CGI trailers for their new gaas from unknown developers were the last straw, playstation used to be so good with showing gameplay of their studios games 1-2 years out and giving their fans something to look forward to.
