Yea, it was way more than I thought when I looked it up a few months ago. It's down to around 10 or 15 now that some have since been released on other platforms (returnal, Kena, deathloop, etc). Doesn't include games on PS4 so GoW/Horizon aren't counted. And I guess you could technically add the PSVR2 exclusives to the list since a PS5 is required and they can't be played anywhere else.
