Looks like it's fairly shitty.
Is PS4 retro? No, but it will be eventually...
Strange time where PS4 is getting sucked into the retro singularity, but also gets regular releases.
I think that's basically "end-game". Many players now are perfectly satisfied with that era of hardware in the face of PS5/X-S, and when all the retro/emulation culture is brought to bear (emulators, ODEs, YT video ecosystem, etc.), "current era" gaming just won't have the arrows in their quiver to compete. FOMO and socially engineering outcomes can only go so far.
I don't think Sayaka believes the PS4 is retro. It was just another console to fix.
