I'm guessing that Adam (Buyatari) is closest to a complete set, though there could be some of you holding out... I've got over 550 first-run PSX games, most of the tough ones (no Suikoden II but I do have Dragonball Z GT). I can't even fathom trying to collect the whole set, but I'll bet ya someday I'll be working on it!
How many PSX games do you have Adam? Have you counted lately?
