From the introduction:
Dungeons & Dragons (D&D), the seminal role- playing game (RPg) first published in 1974 by Tactical Studies Rules, inc. (TSR), is now over forty years old. D&D and its successors have spawned a vibrant industry and subculture. in the last decade, scholars from across the disciplinary spectrum have explored the origins, characteristics, cultures, and player experiences of RPgs. yet, little scholarly attention has been devoted to the meaningful ways RPgs have shaped and transformed society at large over the last forty years. RPgs were remarkably influential on the design of video games—perhaps in ways unknown to many contemporary video game players—and became widely represented in film, television, and other media. They have gone on to transform other areas of society, as well, including education, corporate training, and the military.
