The greatest threat to the success of serious games is inattention to the quality of the player experience. The gamification fad endorses a canard that games can be strip-mined for “useful” bits that, when tacked onto conventional applications, should be expected to have the same effects as true games. This lie exposes a disdain for play and an incapacity to perceive games themselves as useful and worthwhile endeavors. Creating games that achieve great things in the real world while remaining enjoyable experiences instead requires working with the prodigious strengths inherent to the medium. This presentation explores how the native procedurality of video games makes them a potentially ideal way to persuade people to adopt a particular point of view. It will cover the history and modern theory of persuasive games, offer guidelines for crafting arguments based in gameplay, and present a case study of the design of a persuasive game.
