It started out a airplane fighter game...I think some type Red Barron deal, then when star wars came out, they made some modifications,slapped star wars sticker on it and sold it. Never owned it, but most of the early star wars games where boring. This thing now commands a high price in box and is not as common as some other star wars items.
The price guides back then were either way under priced on certain things or overpriced on them. That estimate would be for a dead mint sealed boxed example. Loose probably a couple hundred in mint shape, boxed around 500.
