Historical Game Studies, a burgeoning new field, is increasingly attracting the attention of historians, including digital historians.By exploring Historical Game Studies as part of Digital History, reviewing the birth and evolution of the field, and summarizing the consensus and inspirations in the field, this paper tries to point out that our current Digital Historyis not a direct continuation of Quantitative History.Instead, it is based on the ideal of public history and the concern for media technology, and in this sense, Historical Game Studies could be considered as the continuation and expansion of Digital History.Historical Game Studies explores how video games as digital mass media, have changed the way historical knowledge is produced, disseminated, and received, as well as the public's historical consciousness, thus constitutes a window into the revolution of history in the digital age.Incorporating Historical Game Studies into digital historiography can help clarify the definition and scope of Digital History, and also provide the means to expand and deepen Digital History.
