Here is my Fletcher thesis, looking at how decision-making theories from political science and psychology can be used to better understand free-form games. I can't help but think of this as a work in progress, which is why it has taken me a while to get comfortable with the idea of posting it in its present form. The bibliography (which I may revise and post separately) might be the most useful part of the paper for people interested in this sort of thing.
The Application of Decision-Making Theories to Free-Form Gaming
Comments and questions are very welcome.
(Google Documents seems to have done something strange to the footnotes. Anyone who is interested can email me or leave a comment and I'll send a file in .pdf or .doc format directly.)
