I would sell it on EBAY, no doubt.
I haven't seen one sucker on this board that is dumb enough to plunk down a crisp $100 for a game that was $40 last week, and has about 6 million copies of the PS2 version sold alone. This is CheapAssGamer, so cheapasses aren't going to blow money. I am going to cash off of this since I spent $20 for the xbox version I bought, and I hope to sell my mint, open copy for $60.
