His Majesty the Worm is a new-school game with old-school sensibilities: the classic megadungeon experience given fresh life through a focus on the mundanities and small moments of daily life inside the dungeon.

The game has robust procedures. Characters adventure in the Underworld, rest in role-playing driven camping scenes, and plot long-term schemes in the City at the center of the Wide World.

Often-ignored subsystems, like food, hunger, light, and inventory management, are central to play and actually fun. The relationships between companions, called Bonds, powers the rest and recovery mechanic of the game. Role-playing drives the game forward.
