Georgia Tech’s work in computational journalism has yielded a textbook on designing games for news, along with a blog. As Martha Stewart would say, “This is a good thing.”
Update, April 30: I’ve since read the book and I recommend it. It’s not a design manual, rather, it’s a book that seeks to define news games as an expressive form. It situates news games in relation to journalism history and gaming history. In so doing, it offers valuable insights and provocative observations about the esthetics, ethics and social impact of games of this type.
