I have a copy of of Marvel vs. Capcom 2 for the PS2. I was thinking of trading it in along with a few other games I don't really play too often. Then I see that Gamestop was offering $32 for a trade-in for it. That seemed a bit high, then I see they are sellign it for $69.99. I check Ebay and I see open copies going for near $100, in a few cases for even more. Is this game really that hard to come by?
