[quote name='tolhurst']I am always skeptical about disc only copies.. as I can't imagine how they become disc only in the first place....If somebody who owned it couldn't keep their disc and cases together, they probably wern't careful with the disc, either.[/quote]
Well with a lot of older stuff like this people just didn't think it would be valuable and tossed the case and manual at some point and kept the game in a CD wallet. It's sort of like why most nes and snes games don't come with their boxes and you see this even with genesis games despite having plastic cases instead of paper boxes.
Often times the stuff is also ex-rental which definatley means it has been beat to shit.
