Owl of the not-so-wild
Do you have to actually own a PS4 to get this stuff? If you can just go to the store and add them to your PSN account, I might do that for the day I actually get a PS4 or 5.
You do not have to own a PS4 or PS5. I've already claimed Ratchet and Clank from my PC, and I have neither of the two consoles in question.
