As the owner of a 30-plus year-old video game it's likely that you're someone's grandmother or grandfather, or you truly enjoy now-vintage items. (And you probably dress like a grandmother or grandfather, too.) You scoff at contemporary video game graphics, and miss the days when a controller was "only a joystick and a single red button." People tolerate you because you're probably really easy to beat in a game of Halo (but you hold the top five spots on your own copy of Pac-Man, so yeah), and because you're probably a grandmother or grandfather.
