i think what he's getting at is that discs you can definitely get a return even if it's small. i see some people still trying to sell shares they've been trying to sell for weeks or months. granted some of those people pretend depreciation doesn't exist, but there seems to be limited market on older games nowdays since anyone that wanted them has them already, paired up with people are generally selling games that aren't on the top of anyones "must play now" list (where all them bulletstorm shares at? been looking for months)
ex) i think someone was charging $6 for re revelations not that long ago, and while i think that's a fair price, i would buy it right now at $4. it's kind of that "i don't need it right now ,but for the right price ill take it, and if someone else buys it before i'm ready to then no biggie" mentality with a lot of resells going around
