I don't think you understand what first party means.
Destruction All Stars, Predators, and Firewall are not first party designed games. Unless I missed something and these studios were bought by Sony.
Sackboy I will admit, I completely forgot existed. It was so bland, uninspired, and boring that even after 100%ing the game, I couldn't remember a single thing about it. Returnal is a third person action adventure game. GT7 is the 4th worst game in the franchise. Just barely ahead of Sport, 5, and 6.
Astrobot? Still the single best first party exclusive on the PS5. An amazing experience, but only lasts 1.5 hours. I want more.
Meanwhile we have had God of War 2018, Ragnarok, Uncharted 4, TLOu1, TLOU2, Ghost of Tsushima, Days Gone, Horizon, HOrizon 2, etc. All exactly as I described. It becomes tedious and boring, especially with how every subsequent release adds more and more bloat to the runtime of these games.
Also I am well aware they are working on GAAS titles. All GAAS titles are cancer so who gives a shit?
