The Aesthetics of Video Games

Over on Steven Poole's blog, stevenpoole.net, he's made his first book, Trigger Happy, available for a free download. From his site, it's a "book about the aesthetics of videogames — what they share with cinema, the history of painting, or literature; and what makes them different, in terms of form, psychology and semiotics." I've only read the first chapter, and so far it's very interesting. I've always found it a little difficult to track down more academic, intelligent discussions of video games, so I'm hoping this will prove to be a good read.
