This introduction presents an overview of the key concepts discussed in the subsequent chapters of the book. The book focuses on fan culture published over the past two decades. It addresses the videogame fandom phenomenon, and examines game fandom that is concerned more generally with player culture. The book presents some examples about player activity that intersect with the interests with more focus on the player. It also presents an exciting moment of initial inquiry into currently underdeveloped territory. Fan Studies is a well-established area of study within media studies, and in the judgement is likely to play an increasingly significant role in future game studies scholarship. The book then discusses medium-specific accounts of the relationships that have been developed between fans and a variety of videogaming technologies. Game history has also been a relatively understudied aspect of game studies.
