Forget about price. Forget about artwork condition. Look at the game. Why, why wouldn't I want to buy this?

(Hint- Check out player 2!)

What am I supposed to be seeing there?
All I see on the P2 side is a blue background screen.

Apparently, he relisted it here: http://cgi.ebay.com/TWIN-DAYTON-USA...100058088QQcategoryZ13716QQrdZ1QQcmdZViewItem

The reason I wouldn't buy this is because the 2p game board's 3d chip stopped functioning, there's no 3d graphics on the 2p side, at all. Similar to the now current MAME emulation. How can someone justify that price with the entire 2p side being unplayable?
