In this episode of Tales & Tactics: Beyond the Book, we dive into the Old School Renaissance—better known as the OSR. What began in the mid-2000s as a fan-driven effort to keep early D&D alive through retroclones like OSRIC and Labyrinth Lord quickly grew into a design movement emphasizing rulings over rules, player agency, and lethal, sandbox-style play. We explore how blogs and zines fueled the DIY culture, how retroclones opened the door for new publishing, and how OSR-adjacent games like Lamentations of the Flame Princess and Dungeon Crawl Classics took the ethos in bold new directions. From nostalgia to innovation, the OSR reshaped the hobby and left a lasting imprint on how games are designed and played today.
