In the course of cleaning up the database, I noticed something that I'm not too familiar with, so I figured I'd throw it out there and see if anyone has some insight. We have several PS1 duplicate listings, and upon closer examination of the listings, I've found that most of them have different item numbers. I can see having a different item number for an original release and another for a re-release, such as a greatest hits version, but were there really that many item numbers for the exact same game?
