It has more than one… But it is incredibly lacking still.
But it got Astrobot, Destruction All-stars are both new IPs. There is also Spider-Man 2 and Ratchet and Clank Rift Apart for first party. And you can throw in Stella Blade and FF7 Rebirth for now as well.
I believe everything else is remakes or not exclusive to the PS5.
Edit - ohhh scratch Ratchet and Clank off as well, that’s on PC. I thought it was the PS4 one that came to PC, but it is Rift Apart.
Wikipedia is only listing PS5. Spiderman and Miles Morales were PS4, but Spiderman 2 is only on the PS5
