I don't know if the seller really new the value of what he has. Ys IV in his sell list is $85 and every Duo game is exactly $50? I really do hope someone snagged that game just to have and play. I'd hate to see it resold on ebay. Congrats to whoever bought it.
Yeah, I paid less than 20.00 for Ys IV last Summer. I'm guessing the seller operates on the half price books method of pricing things. Example most SNES carts are 4.99, there is one Super Famicom Game, it's in the display case with a handwritten note on it saying "Japanese Horse Racing Game Rare! 30.00 FROM JAPAN". A lot of people have no idea what the value of games are.
