I have bought over 15 copies of Grand Theft Auto: Vice City.
I've returned about eight of them because they didn't work right off the bat.
The others have all stopped working over time.
I've been getting them since the original. I got the Greatest Hits. Then, I got another version where I believe the word "Haitian" was cut out.
They all stopped working after a few months. And no, none of my other games ever did this.
I don't have a PS2 anymore, but I'm curious as to why this happened.
