Ian Bogost is a professor, videogame designer, and author. In his book, Persuasive Games, Bogost argues that different mediums have different "procedural rhetorics." These "procedural rhetorics" convey different world views. In Persuasive Games, he uses the example of video games to demonstrate this point. He discusses how the procedural rhetorics of video games have ramifications in the realms of political discourse, advertising and education. Some of the games described in his book were designed by Bogost's own company, which is also named Persuasive Games.
