In total, it's 66 pages of content devoted to a single masterpiece, including revised text from anatomyofgames.com as well as new supplemental material.
The site currently hosted at GameSpite.net has been online in various incarnations since 1996, although it's only in the past few years that it's become a home to smart, incisive critiques by a loosely-associated team of writers.
