I don't think I've ever sold a game, although I lost a couple (or swapped them with friends, maybe) when I was a kid. I guess I could lose a few stinkers from my collection (aside from awesomely crap games like Star Wars Episode 1: The Phantom Menace on PS1 :D), but most games are worth so little money that I might as well save the effort and keep them. The few I have that are worth something are the ones I'd never sell anyway. :brickwall :D
