I just found a link to this book from the ctheory site. It has its own companion website here: http://www.criticaldigitalstudies.net/
Of particular interests are articles by N Katherine Hayles called ‘Traumas of Code’ and Donna Haraway called ‘A Game of Cat’s Cradle: Sign Studies, Feminist Theory, Cultural Studies’.
Also the article ‘Warcraft and Utopia’ by Alexander R Galloway is published here. This was published originally on ctheory and can be read here. Its a good place to start for people trying to think about how critical theory can be applied to World of Warcraft.
I’ll be ordering this from Amazon sometime soon.
