I wrote a paper with Anders Tychsen, Michael Hitchens and Susana Tosca which is now published:

Abstract: The Pen-and-Paper role-playing game is a successful example of collaborative interactive narrative. Meanwhile, computer-based role-playing games, while structurally similar, offer quite different narrative experiences. Here results are presented of an experimental study of role-playing gamers in Pen-and-Paper and computer-supported settings. Communication patterns are shown to vary significantly on measures such as the share of in-character statements and the share of dramatically motivated statements. These results are discussed in the light of differences between the two gaming forms and finally some design implications are discussed.
