Dungeon Delvers Twelve (DD12) is a generic fantasy role-playing game currently in creation. The core tenet of its system is to streamline the rules of the 1991 game DungeonWorld, allowing players and GMs to use the sections that suit them for their complexity and use the DD12 streamlined sections for the rest of the game.
Dungeon Delvers Twelve was created to give access of the Dungeon World system to the younger audience who prefer less crunch in their roleplay experience, but still allow OSR-styled gamers the ability to play the original DungeonWorld rules as well.
DD12 was due for a Kickstarter release in Feb 2020, but due to the Corona Virus, has been delayed until printing and shipping costs may be reduced, possibly 2021.
