From the About Us page;
"Today people can read a book, watch a movie, or play a video game...but soon anyone will be able to enjoy a storyworld.
Computer game design veteran Chris Crawford has teamed with science fiction writer Laura J. Mixon to found Storytron, a company devoted to the creation and publication of works of interactive storytelling.
Storyworlds are a new form of computer entertainment developed by Storytron, Inc. Using our free authoring tool, SWAT, creative individuals with a story to tell can script their own sets of Actors, Stages, Props, and a web of potential interactions known as Verbs. Players seeking a unique new form of computer entertainment can play those storyworlds, engage with the Actors, and explore a wide range of choices and behavior in the dramatically rich environment developed by the author of that world.
