I found a super rare PS3 game

Oh wow 900! that's crazy! Never thought there were that many out there. 480 is really impressive! Japanese editions are usually packed with nice things, it's why I enjoy those the most. I wish you good luck completing your database!
I guess I don't collect anything specific. I usually buy games that I enjoy, but since most of them are jRPGs, I guess you could say I collect those. I tend to nail them down one series at a time. It can get expensive for some of the older ones.
