Dungeon World is a new, award-winning role-playing game system written by Sage LaTorra and Adam Koebel. It is a version of fantasy adventure that uses the rules from Vincent Baker's Apocalypse World as its foundation. It has a website here.
Our current Dungeon World setting is pulp science fantasy, with plenty of alien planets, spaceships, and rayguns. You can read summaries of our games, starting from Robot Invasion on the Dungeon World campaign page.
Lord Stefan slew the Dragon and routed his army of goblinkind, but could not stay to consolidate his hold on the ruined kingdoms of The Black Peaks. Now mercenaries, charlatans and adventurers of all stripes have flocked to the area! Throw oil, sacrifice retainers and separate monsters from their treasure the old fashioned way (ie Charm, Sleep & Treachery).
Strap on your azoth, saddle up your zorse and charge across the Iridium Plateau in search of inscrutable artifacts, forgotten spells, or just seriously potent intoxicants. Battle unspeakable horrors, explore the Melted City, or get lost in the Slime Lands. But steer clear of the Limb Pirates. And watch out for radiation storms!
