There is more than 1. Flower, Unfinished Swan, and TLoU is the ones that come to the top of my head that is Sony IP. This generation has just really been bad about it with the majority of Sony's top rated games being remasters from GTA, Rayman, Diablo etc The way i interpret is that Sony fans have been touting Sony's library but when you look at it theyre filled with remasters and indies.
On the other hand i do agree that this is an over-reaction from all three fanbases. Its a remaster which shouldnt cause a big deal. Honestly i believe its because many people dont believe PS4 deserves the sales it gets when it arguably has the worst library of the three consoles.
Either way Bloodeborn is in 4 days which looks amazing. So everybody can relax. Either buy it or dont, but there is things to look forward to
