I wouldn't say it has been a bad generation for Sony.
You see the PS5 reveal with Spiderman Mike's Morales, Sackboy, Demons Souls, Returnal, FFXVI, Ratchet and Clank, Death loop and Jena all exclusive and compare it to the Xbox one, wich I don't even remember but probably was something with Craig, multigen Forza and Spencer with a big belly saying this is the year or Gen of Xbox and it was clear who was gonna wipe the floor with who.
They have had big problems with the price but like everybody else, it's just a industry a worldwide, issue.
And in terms of FP output, they are on par with the PS4 Gen. They are badmouthed because some were intergen and the ports to PC, but it's not like they haven't released onpar with the 5 first year of the PS4 Gen.
They have provided great accesories, developed PSN+ even further etc. The console itself is super slick, silent, cold and reliable.
All in all a good generation for them, but they are now the target for most of the haters (specially those whose platform is tanking or dreaming to take over) speech because on the exclusivity of games.
Now haters have to make up their goddam mind. They say exclusives are the worst yet at the same time say Sony is done for because temporal exclusives and no games, and when, they release games they say that doesn't matter because multi with PC in some years, at the same time everything just bought by MS is Xbox output and not being exclusive at all even fir one second is great and everything is fine and Xbox deserves better. Who can understand that?
