Maps play discerning roles in video games and have multiple functions supporting gameplay from communication information to navigational tools. However, our body of knowledge regarding game maps, while growing, is still limited ? especially from a cartographic perspective. In this paper, we contribute a classification of game maps developed from a sample of online articles and posts dedicated to video game maps. We discuss the developed categories and present examples to illustrate the varied manifestations of maps in games. Based on our review we further discuss how they can be designed and function to stimulate playfulness and present avenues for future research.
