I'm in agreement with you. I've heard that Persona 4 Golden will not come out on any other platform but I agree that at least the original Persona 4 should be on PSN. Anyway we can get Sony/Atlus to at least do that?
As Capt said, you should contact the developer / publisher to request one of their titles to come to PSN. Especially if it is a game that was not created / published by Sony.
Aside from contacting the dev / pub, you could also make a post on the "blog share" page, here.
It is a much better way to get your thoughts / requests read, rather than posting them on the community forums.
Please put your trophy profile as private, otherwise I might have believed you own a PS4 (thanks for the fake pic though)."
As I said, it's not FULL. Go look in their store, its missing some titles in PS1, and a LOT of PS2.
Don't bother arguing with him. He's the type who's never satisfied
