I can only think that there are some sort of bidder shenanigans going on there. Looking at past sales for complete copies of Shining Force, the max seems to be in the $35 -$40 range. How or why this particular one, which is missing it's original case, has reach over $13,000 is beyond my understanding. Looking at the bid history, there's a lot of bids from the same zero feedback bidder and one other with a low feedback rating. It's been my exerience that crazy high bids from zero or low feedback rating bidders is usually a sign of someone playing a joke on the seller for whatever reason. Perhaps there's something uniquely special about this particular copy of the game, but I don't see it...
