I had a NES back in the 80s and had never heard of Stadium Events until now, but TIL that it's one of the most rare NES games in the world.
So much so, that a sealed copy of Stadium Events was sold to a private buyer for a huge $41,977. The seller went for a traditional auction on eBay but the person who won didn't end up paying, so the seller contacted the "serious buyer" who coughed up the massive $41,977.
This isn't the first time that copies of Stadium Events have been sold, with a sealed copy being sold in 2015 for $35,100 and another sealed copy in 2010 sold for $41,300.
Stadium Events was released in very limited copies in 1987 when it was paired with the Family Fun Fitness pad, and is one of the first exercise games.
