In this study, we contribute to the CSCW literature regarding eSports by performing a comparative analysis of two different action games, focusing on how cooperation, communication, and competition take place in each one of them. To do so, we perform a semi-qualitative study involving interviews with professional and amateur players. Then, we analyzed the results of the fieldwork, which consisted of a 31-question questionnaire with 65 valid respondents. Moreover, we discuss and highlight the relationship between our results and other CSCW-related works focusing on our research questions. Among our findings, we can highlight the specialization of work in different eSport teams, the importance of non-verbal communication during matches, and the interplay between competition and collaboration in the same team.enesportsText/Conference Paper10.18420/ecscw2018_112510-2591
