A rare, original copy of the first game developed by the legendary husband and wife team of Ken and Roberta Williams has just hit eBay, and despite being little more than a floppy disk and a slip of paper inside a plastic bag, it's already set to fetch thousands of dollars after just one day on the auction site.

Later printings of Mystery House already go anywhere from a few hundred dollars to a couple of thousand on eBay, but just one day after posting this original copy has already eclipsed $4,000. And with
