In this episode of Tales & Tactics, our Beyond the Book series turns to hidden information and randomness as design tools in tabletop gaming. We explore how fog of war and hidden unit mechanics in board wargames create authentic battlefield uncertainty, forcing decisions under incomplete information, and how random tables and GM driven dice outcomes in RPGs produce genuinely surprising results that no amount of preparation could script. Across both genres, the throughline is the same; well designed uncertainty doesn’t undermine player agency, it deepens it.
