Yeah but without anything to trade do you really wanna do that?
I mean it's possible some stuff might turn up at work or whatever, not highly likely but...a few weeks ago I was talking about kotor and how my copy wasn't any good (god knows why but the inner ring wouldn't verify), within a couple of days another copy turned up at work and that game isn't easy to find here now.
And that copy of Jurassic Park OG PS2 I got a while back that's rare as hell here, even if you're willing to spend top dollar to purchase it
Just a couple of examples.
