Far too many, I've been buying physical games nearly non stop since last November, I'll try to take some pictures later of what I bought since June, but I've also been buying some dlcs and games before the PS3 store closes as well.
I've been keeping a list for myself to know what I got so far, so I'll just copy paste it here. What is written under the game name is what I got/purchased.
