Kotaku - On a warm evening earlier this month outside a cafe in Buenos Aires, Colin Northway took a sip of his drink and told me about the rarest video game in the world.
He was making the game, he told me, and he was excited about it. He didn't call it the rarest game on the planet. That's just how I would come to think of it in the days that followed, as Colin's unusual game concept took root in my brain and become something of an obsession. He was trying to do one of the most unusual things I'd ever heard a game developer attempt.
