Cooperative World Building
Cooperative World Building is a term that refers to the process in which the GM and the players share ideas for the world in which the game takes place. This means that, while the GM is responsible for the story and the integrity of the game as a whole, the players are a part of the world creation process.
Here’s an example: Someone wants to play a dwarven battlerager. He has an idea about what is going on in dwarf society and says, “Hey GM, what do you think about this?” The GM says, “Hey man, cool idea. I wasn’t really thinking about dwarven society because I was so busy trying to create an enjoyable main plot. Let’s work that into the story.” So we chat and come up with some ideas and that becomes a part of the canon for our story.
See? That’s how it works. It’s easy and anyone can do it. This means that, instead of having me force feed you information about the world, we can build this world together to give you interesting and, potentially, plot centric places to go. The idea is for everyone to have fun and, sometimes, the GM might not know what would be the most fun for you. Cooperative World Building allows you to have a say in what sort of place your characters live.
