I was running a HERO game at the local university gaming club a year or so back, and met a guy as I was coming back from a vending machine run. Upon seeing all of us sitting around a table in a lecture hall, he asked what we were doing.
"Oh, we're playing Champions," I replied. At his blank look, I elaborated, "It's a role-playing game."
He gave me an amazed look. "You mean like, Dungeons and Dragons?"
"Sort of," I replied, expecting to explain the difference between superhero and fantasy RPGs.
"You mean that people actually play with pencil and paper and not on a computer? That's so archaic!"
