In this introduction, game studies is argued to be a force of innovation for cultural studies. While game studies, as it has developed over the last 10 years, fits well within cultural studies' methodology and theory, it does more than benefit from cultural studies as a 'mother discipline'. Game studies proves itself to be a strong force, especially in its productive use of political economy to analyse games and gaming as a (new) cultural form. Building on a descriptive taxonomy of games and gaming by both genre and 'platform', this is an introduction to games and gaming for those with a cultural studies background. While ideally, game studies will develop also as cultural critique, this is a far cry from dominant practice in the gamer community. Gamers tend to be 'hand-in-glove' with the industry. It is high time for game studies to turn a critical eye on itself.
