Personally, I collect videogame music mainly because I want to hear again some tracks without having the hassle of replaying the game. The only thing that concerns me is the CD's condition, for that reason I used to do WAV rips of each disc I've got... That's it, I don't care if the package/content get damaged over time, or there's something missing.... Never wanted to trade or sell anything, if I'm lucky enough to get my hands on something, I keep it... Can't leave my precioussss
