The owner of the unbelievably rare, possibly unique prototype Play Station revealed the device is going to auction. Come February, someone is going to go home with a precious piece of gaming history.

In case you don’t know what I’m talking about, in the late 1980s, Nintendo and Sony worked out a deal to create a CD-based add-on to the upcoming Super Nintendo, as well as a hybrid cartridge/disc console that would have been called the “Nintendo Play Station.” Nintendo, however, worked out a more favorable partnership with Phillips, which it revealed at the same Consumer Electronics Show where Sony revealed the Play Station. High drama, to be sure, and a big “What if” moment for gamers.
