Stadium Events has officially taken the crown as the most expensive video game ever sold. A sealed copy of the NTSC version of Stadium Events sold on ebay for $41,300!
This is more expensive than Nintendo Campus Challenge which sold for $20,100 or Nintendo World Championships Gold which sold for $21,400. The two previous record prices.
The seller of the game lives in Olathe, Kansas and had purchased the game brand new at a Richmond Gordmans, a department store in the midwest, for $29.99. They never opened it after they realized it needed a power pad to play. They never got around to returning it either (maybe the smartest decision they ever made).
The seller had a total return of 137,568% or 37.9% per year on this "mistaken" Stadium Events purchase. That's a better return than Apple, Microsoft, or almost any other investment you could make at the same time.
