How's the rarity/scarcity/demand for the packaged DLC-in-a-case version of Marvel vs. Capcom 2 for PS3? I bought one 2+ years ago and still haven't opened it. At this point I was thinking of just selling it. It was a Gamestop exclusive, too, IIRC.
Someone on ebay has one for sale for $150, but it's been sitting there for a while, and not selling. I think the game itself had a low print run but isn't much in demand because you can just download it off PSN.
