Alexnder R. Galloway uses comparisons between film and gaming to bring up points for his breakdown of a video game world. In the first chapter he describes the use of the diegetic and non-diegetic aspects of a game to separate how we see a game. These different acts are described for specific games. “The heads-up display (HUD) in Deus Ex is non-diegetic, while the various rooms and environments in the game are diegetic”. (Galloway, 8) To relate that to a game that I might know is more of a difficult challenge. I think that with his meaning; in the game Guitar Hero the start and pause actions are considered to be non-diegetic while playing the correct notes on the guitar would be a diegetic act. This is a concept that he says is present in film and is where he draws his theory. He refers to many specific movies such as Hitchcock’s Rear Window in the second chapter when talking about point of view (POV) camera perspectives compared to subjective camera perspectives. A first person subjective view is one that shows exactly what a person would see if the camera were the persons head. The POV first person perspective is a more generalized view of the surroundings the person is looking at. The thing that I like about his analysis throughout the book is his correlation of one medium to another. Movies are very similar to gaming in how they are created, viewed, and manipulated. His book takes many avenues to show how these worlds are intermingled.
