The only disk that I ever had get destroyed because of my own incompetence. Was a copy of the first season of Stargate SG one, it was actually the first disc of that season. And what happened was I left it outside of its case, in an area that allowed the sun to go across it every single day for about a month and a half.
It discolored the disk, and also made it unplayable , had to buy a new one.
That was fully on me.
Many of my games that I played in the late 90s and early 2000s I would play over and over and over and over again, never scratched them.
