A mom in North Carolina listed an NES and five carts on eBay last week for $9.99. Final winning bid: $13,105. One of the games in the lot happened to be the ultra-rare Stadium Events, in its original box.
What's Stadium Events? Well, according to its Wikipedia entry, it was a Bandai exer-game that used the Power Pad, originally known as the Family Fun Fitness mat; it's considered the rarest licensed NES game made available in North America. It was only released in a northern U.S. test market in 1987. In 1988, Nintendo bought the North American rights to the mat, re-released it as the Power Pad, and anything Family Fun Fitness branded was taken off the shelf and destroyed..
Fewer than 2,000 copies of the game were believed to have been produced, only 10 complete specimens are thought to exist, only one of them factory sealed.
It's not clear if the seller knew what she had on her hands when she started the auction. If not, she sure found out once the questions about Stadium Events started pouring in and the bids soared north of $1,000. Either way, I'm sure she is delighted to get 13 grand for something that had been sitting in a closet for several years.
