Too many times I have heard people recalling "Pinball Deluxe" as one of their favorite games from decades ago. Or "that police chase pinball". Can't forget people looking for the Caddyshack pinball either (which could reference more than one game actually).
What really infuriates me is when I'm standing in front of a game and people ask (and point to the PF) if I've ever made the ball "go up there".
