An anonymous reader writes: This year is the 40th anniversary of the launch of Dungeons & Dragons, and it's getting a lot of mainstream attention. Long-time and former players are examining the game's influence and its legacy, even as it's being introduced to yet another generation of kids. "For countless players, Dungeons & Dragons redirected teen-age miseries and energies that might have been put to more destructive uses. How many depressed and lonely kids turned away from suicide because they found community and escape in role-playing games? How many acts of bullying or vandalism were sublimated into dice-driven combat? ... How many underage D.U.I.s never came to pass because spell tables were being consulted late into the night?" Meanwhile, as people who played the game long ago have grown into adults producing their own works, our culture has reaped the benefits of D&D's influence. "The league of ex-gamer writers also includes the 'weird fiction' author China Miéville (The City & the City); Brent Hartinger (author of Geography Club, a novel about gay and bisexual teenagers); the sci-fi and young adult author Cory Doctorow; the poet and fiction writer Sherman Alexie; the comedian Stephen Colbert; George R. R. Martin, author of the A Song of Ice and Fire series (who still enjoys role-playing games). Others who have been influenced are television and film storytellers and entertainers like Robin Williams, Matt Groening (The Simpsons), Dan Harmon (Community) and Chris Weitz (American Pie)."
