QuestWorlds is a roleplaying rules engine suitable for you to play in any genre.
It is a traditional roleplaying game in that there is a GM and players. The players play characters, each guided by the internal thoughts of their character as to what decisions they make, and the GM plays the world, including non-player characters (NPCs) and abstract threats.
It features an abstract, conflict-based, resolution method and scalable, customizable, character descriptions. Designed to emulate the way characters in fiction face and overcome challenges, it is suitable for a wide variety of genres and play styles.
It is a rules-light system that facilitates beginning play easily, and resolving conflicts in play quickly.
We refer to a rules-light but traditional roleplaying game as a storytelling game, after Greg Stafford’s definition in Prince Valiant.
