His Red Box Set Inspired Stranger Things and Sold 40 Million Copies in the 80s.

Director's Dungeon

In this episode of Directors Dungeon, I sit down with Frank Mentzer—a name etched deeply into the foundations of tabletop gaming. Best known as the author of the Red Box edition of Dungeons & Dragons, Frank is more than a game designer.

He’s a storyteller, an archivist, and a witness to the formative years of a cultural movement. Over the course of our conversation, he opens the doors to a lifetime of design, discovery, and one of the largest privately held collections of games in the world—more than 10,000 and counting.

We begin with “the hoard,” as he calls it: an astonishing array of vintage board games, RPGs, and ephemera stored across multiple locations. But this isn't just a collector's habit. For Frank, it's a record of the 20th century told through mass-market games—their box art, their design sensibilities, and the assumptions they made about who played and why. From post-war optimism to television tie-ins like Bewitched and Gilligan’s Island, the collection traces the contours of American culture long before digital entertainment took over.

But the conversation doesn’t stay in the past. Frank walks us through his early days at TSR, where a job posting led to a career that would help define the hobby. He reflects on his role in rewriting the D&D Basic Set—transforming it from a niche war game into an accessible entry point for millions. We talk about the unexpected turns: editing Gary Gygax’s work, running tournaments at Gen Con, and building worlds designed for collaboration over conflict. His philosophy on gaming emphasizes cooperation, storytelling, and world-building over conquest—a deliberate departure from the competitive mechanics that dominated the wargaming scene he came from.

As someone who has played and designed for nearly five decades, Frank offers rare insight into how the tabletop space has evolved—and how some of the best ideas were lost, shelved, or stolen along the way. He discusses the archival material he’s preserved, including manuscripts, internal memos, and original drafts from TSR's most pivotal years. Whether these will be donated, sold, or published is still undecided—but the urgency to preserve them is clear.

More than a retrospective, this episode is a meditation on memory, legacy, and the quiet labor of keeping a creative history alive. Frank isn’t chasing a final payday. He’s trying to make sure the stories—and the stuff—don’t disappear. It’s a conversation filled with humor, candor, and a kind of awe that only comes from someone who’s seen it all, yet still finds joy in a dusty game box or an obscure ruleset.

If you're a fan of RPGs, cultural history, or just love a good story well told, this episode captures something essential about why these games matter—and why preserving their history is a project worth doing.
