Short, director of KitFox Games, and Adams, the independent co-creator of the popular game Dwarf Fortress, have edited a substantial collection of essays providing concepts and practical application of procedurally generated content and algorithms for game design purposes. Procedural generational the method of creating data via algorithm rather than by hand—is a principle developers can harness to allow the game to generate its own content (settings, objects, and stories) using a series of rules. This method can result in considerable savings over the more traditional game design. Unlike Procedural Content Generation in Games (Shaker, Togelius, Nelson, 2016), the material here is authored by independent developers (with one exception from Blizzard Entertainment), so the information is more accessible and actionable. The book should enable game developers evaluating procedural generation for their games to make an informed decision whether or not to use it. Those with a background in computer science or who are already using procedural generation may learn something new from the contributors’ experiences and methodologies. --A.
