I work at a thrift store and am 28 but look about 19-21 depending on who's guessing. Anyway this one older lady, had to have been at least 60, called me over to the puzzles and handed me something with small print that she was struggling to read.
I looked at it and knew right away that it was an Atari Flashback. Those systems that have a dozen or so Atari games on one small console. I, assuming she had no idea what that'd be, explained to her that it's "This Atari video game thing from the 70's." Her face lit up and then she went on about how much she loved to play Galaga and Space Invaders.
She said, "I'm surprised that someone your age even knows what that is." I told her that I thought the same thing about her. So we both laughed and ended up talking about Atari for the next 10 minutes.
Tl:dr: Don't judge a book by its cover. Video games aren't just for young people.
