In Ruins is a GM-less dungeon-building game for 1-6 players. Part collaborative story game, part tactical network-building game, players tell the story of a castle as it is built, falls into ruins, and is taken over by rival factions. In the ~2 hour game, players will create a dungeon, fully stocked with competing factions, hazards, monsters, and NPCs, that can then be explored with their fantasy TTRPG of choice. - Full play-time of 1.5-2 hours can be divided up over multiple sessions. - Includes story-game aspects where players collaborate to create the history of the castle. - The process of laying out the castle’s rooms in the first round and then ruining them in the second round creates the dungeon. - Players control classic fantasy factions (such as Kobolds, Cultists, and Undead) with asymmetric abilities as they vie for dominance over the dungeon.
