Pong. I played it downstairs in the Sears Department Store in Concord New Hampshire. It was where they kept the appliance and electronics demos. It was hooked up to a television. No idea the price but I was fascinated and desperately wanted it. I was, I dunno, maybe nine years old. Long time ago. Many many years later, my first home game console was a Sega Genesis. Loved that machine. Many years later, a Sony Play Station One. Nothing after that. I have never had money, really resent the high price of consoles and high price of games.
