Abstract

Massively multiplayer online games have become a large industry with millions of users playing every day. Matchmaking is used to group players in a fair game for multiplayer online video games. In this paper, we examine how well matchmaking systems create matches that are enjoyable for players in the popular multiplayer online game League of Legends. We collected data about the matchmaking system of League of Legends by surveying players before and after a game and collecting statistics about their games. We analyzed this data and came to several conclusions: queue times rise with rank but are generally quite low, the main factor reported to affect the game outcome is player skill, and players generally enjoy games where their team is better or the game is even.
