Yeah, I agree with this sentiment. Even including last gen, a PC/Playstation was a pretty good combo. There were enough quality Playstation exclusives to justify a PS console, and there were some genres and styles of games I could only get on PC. Both together, I was pretty happy with the games I could pick from.
This gen, I have a Playstation 5 that's severely underworked. There are very few exclusive games on it, fewer still worth playing, and apparently the two lists are getting smaller every day, rather than getting bigger. I'm pretty disappointed so far and I don't see myself buying any Playstation console after the PS5 unless things change significantly.
