I don't think most teenagers really care about retro gaming unless they were introduced to it by an older sibling/parent. Why would people born in the 2000s-or-so have any knowledge of an arcade game from the late 1970s? Unless they're devout fans of gaming, then chances are, they have zero interest in something that's not the latest and greatest. Old stuff like Tetris or Pacman are still relevant, but when was the last time you saw a Space Invaders game?
Edit: To clarify, I'm 19. But I grew up with NES/SNES/Genesis games. Had I not gotten those retro systems passed down to me by my parents, I'm sure I would have just had a N64/PS1 like most other kids and would have grown up playing 3D games, not having an understanding or connection to 2D sprite based games.
