Shared Story Worlds Design Primer: Scott Walker
Scott Walker defines a shared story world as "an entertainment property designed to allow audiences/fans/consumers to collaborate and participate in the creation of content in the entertainment property." You can learn more about shared story worlds on Scott's sharedstoryworlds.com website. Or, if you want to learn more about the projects Scott is currently working on (or to hire Scott as consultant as you build your own shared story world?), you can find him through his Brain Candy LLC.
