Does anyone remember a Wired (?) story from the earliest days about a teenager who got mixed up in a geek subculture and disappeared into sewers under the city? A quick search on their site didn't really yield what I think I remember.
This might interest you: I watched the quite disturbing documentary "Dark Days" a few years ago about homeless people living in subway and sewage tunnels under New York. They had built small apartments down there and even had electricity.
Here are the first 10 minutes on YouTube: https://www.youtube.com/watch?v=dh4s78Db5OQ
Not as far as any link between the disappearance and D&D, no:

> and there was a Tom Hanks movie about it.
Mazes and Monsters, the novel and the movie, were inspired by the (false) story of the event.
Had no idea the movie even existed.
