Austin Community College offers a technical two-year certificate in videogame design, which, given its location, is not surprising. What caught my eye was the quality of the interactive audio syllabus and some of their lecture slideshows, which are online. Especially interesting was "Writing for the hero with 1,000 faces" (by the writer for Gears of War), which founded its writing wisdom on the theory of mirror neurons. Also "What Vegas can teach MMO designers" (by a designer/programmer of Ultima Online and Shadowbane) mentioned what lessons interior design can teach to games.
The audio syllabus, and other educational institutions that caught my eye are linked here.
