The one and only Nintendo Campus Challenge is back on the market after one year. Last summer I sold this game to a collector for $20,100.
That same collector has it listed on ebay with a starting price of $88,888. The seller knows they won't get close to that much for it but wants to see some offers from interested parties.
If your interested, submit an offer. Maybe the seller will accept and you'll own a one-of-a-kind video game collectors item. Or you can buy a reproduction for $75.
