This thesis covers the history of the MOBA (Multiplayer Online Battle Arena) genre by creating a chronological historical timeline of some of the most catalytic titles. It also delves deeper into the dynamic between modders and companies and how that dynamic changed as the genre evolved. All of this is analyzed through a political economy lens, to see how the power structure and monetization plan for the games in the genre has changed over the years. The research was conducted by piecing together relevant academic papers, with popular sources to construct a credible thesis on the MOBA genre's evolution. One of the key points from this research is how monetization has changed from the beginning of the genre to how it is today. Roughly 20 years ago, when the genre first started, monetization was more straightforward, a one-time purchase for the game. Today, most games in the genre are free-to-play, while containing in-game purchases such as cosmetics and character unlocks.
