I'm slowly building up a PS2 collection. All my games seem to have disappeared over the years, guess I traded them in after finishing them, but I've been steadily regrowing it. My most recent purchase was from CeX, a used games/DVD store. The oldest games sold are PS2, at least in my city. As you can see, I picked up an Alone In The Dark game, Jak II and Ratchet and Clank. My PS2 backlog is Haunting Ground, Second Sight and Silent Hill 3, which came from my next most recent splurge, so it could be a while before I open these up.
I've got a lot of games on my bucket list, the ones I'd most like to get being the original Onimusha game and Dragon Quest VIII.
