Before Wii Sports and Wii Fitness there was Stadium Events. Released in the U.S. in 1987, it was one of two games made to use Nintendo’s short-lived Family Fun Fitness mat, a mat on which gamers could use as a control by running on it. Stadium Events failed to do well, so Bandai yanked if off shelves and rebranded it World Class Track Meet. Apparently, this made it one of the most rare video games of all time, allowing a guy who had a copy sitting in his basement for 20 years to sell it on eBay for $41,300. Win.
