Mazes and Monsters (1982)

"This one isn’t a high school movie, but more a college-age movie. It’s called Mazes and Monsters and it stars Tom Hanks. It’s about the dangers of role-playing games, and if you play these role-playing games, you’ll lose touch with reality. Tom Hanks is a kid who gets too into their version of Dungeons and Dragons, which they call Mazes and Monsters. He loses touch with reality and thinks he really is on the quest, and disappears into New York City. His friends have to try and find him. It’s definitely worth checking out if you can find it. It might be one of those movies that just disappeared. I think it was a made-for-TV movie, but it’s always affected me. I saw it when I was a kid on the Saturday afternoon matinee movie, and it just has this ending that is so bleak that I’ll never forget."
