Toward Successful Esports Team: How Does National Diversity Affect Multiplayer Online Battle Arena Video Games

Abstract

Today, esports teams in multiplayer online battle arena (MOBA) games are often composed of players from around the world. The paper asks whether a greater national heterogeneity of professional esports teams means their higher effectiveness. Desk research data of 13 tournaments of Dota 2 game held in 2011-2018 is used to calculate the teams' win ratio, i.e., the ratio of skirmishes (in all matches) won to the total number of skirmishes (match is a series of skirmishes). Hence, effectiveness is understood not as ranks or matches won, but as the lowest possible number of lost skirmishes. Multinational teams achieved a higher win ratio, compared to nationally homogenous teams and the analysis includes the role of coaches' nationalities. Working groups, cognitive diversity, and similarity/attraction theories are used to signal potential reasons and consequences of diversity on team performance. This exploratory study indicates future research threads on esports teams' national diversity.
