I have a mint, scratch-free Grand Theft Auto: San Andreas for the PS2 that I'd like to trade for a mint, scratch-free Grand Theft Auto: San Andreas for the Xbox.
I can't speak for anyone else, but I wouldn't bite here. The PS2 version is much more common, and if there ever is any increase in value - not bloody likely for any of the versions of the game - the Xbox version would be the one that sees it.
[quote name='-Never4ever-']You're going to have to at least add something else in to even out the trade, I highly doubt someone's going to downgrade for absolutely nothing.[/QUOTE]
I was the one that swapped GTA 3 & VC with him, and would have swapped SA as well had I not been stupid & traded it in to Rhino the day before. I have no Xbox, so having a version of the games I can play > having a "superior" version that just sits on the shelf.
Anyway, best of luck to a great trader on finding this - and if you decide to trade your PS2 GTA:SA for something else, let me know.
