As a further example of how a game like that can go more for used than new. Pinball hall of Fame: The Williams Collection for Wii jumped in price in December. Turns out, that Amazon stopped carrying it for a week. The used prices instantly jumped to $60 and stayed that way until they started selling it again for $10 OVER MSRP.
This website only tracked that the game went up in price, they don't show the max price which was WAY over MSRP.
