Nintendo PlayStation PSone Retro 1

On display at the Portland Retro Gaming Expo this weekend was a real treasure: the Nintendo PlayStation. The disc-based edition of the Super Nintendo system was produced by Sony in collaboration with the House of Mario, but never saw the light of day after the two Japanese giants had a difference of opinion. A prototype unit did, however, show up in someone's attic not too long ago.

And now it's being taken on tour so that others can see the piece of memorabilia up close. We were lucky enough to get some eyes-on time with the console this weekend, which was pretty unreal. Looking at the grey hunk of hardware, it's difficult not to ponder how different things could have been; Sony eventually launched the PlayStation on its own, but what would the world be like if it had continued collaborating with Nintendo?

We'll never know.
