What is Roleplaying?

Roleplaying games, are essentially collaborative, improvised storytelling created by the players, with rules to guide situations where success or failure makes a difference. Using dialogue and description, the participants describe and explore a world and the beings that inhabit it. They create stories together, guided by game rules to ensure fairness and some degree of order and consistency.

In Chaosium games, you and your friends are characters and one of you is the gamemaster. In Call of Cthulhu the character are Investigators; in RuneQuest they are Adventurers; in 7th Sea, Heroes; and in Pendragon, Knights. They are described in terms of their abilities: numbers and terms that indicate how strong, smart, charismatic, or fast they are, and how skilled they are at what they do.

The gamemaster is a combination of referee and director, interpreting the setting and the creatures and people that inhabit it and representing it to the players. The players act in the world through their characters, and the gamemaster adapts the story to their actions—successes and failures—as the collaborative story being told in the game unfolds. When there's a chance that an action the characters or the gamemaster attempts might fail, you roll dice to determine whether luck smiles on you or whether you'll have to keep trying!

Starting Small
Board Games and Fiction

If you are new to the Chaosium games, and even new to role-playing completely, this is a great place to start. We would like to think that roleplaying is the perfect blend of board game randomness and replay-ability with the depth of fiction. To get you started, you can check out the board games we have for most of our major lines, or read a great assortment of fiction.
