The first commercial TRPG, Dungeons & Dragons, is naively designed. Veteran players are full of horror stories about antisocial quests for gold in implausible environments, a far cry from fantasy literature. Nonetheless, it is possible to salvage the notion of TRPG dungeons for use in great board games like Descent. Likewise, the dream of the mythical well-designed board/RPG hybrid where the tactical gameplay does not undermine the storytelling will live on. So I built a modular dungeon.
