We present an exploratory factor analysis (followed by a validation study) with which we developed a 25-item questionnaire assessing five different viewer types. In this paper, we wanted to understand whether viewers’ motivations can be formulated as viewer types and systematically measured. Previous scientific work has revealed that different motivations drive people to become viewers, which apparently impacts how they interact with the offered features and which streamers’ behaviors they appreciate. Streamers of gaming content broadcast how they play digital or analog games, attracting several thousand viewers at once. While the actual content that is streamed is diverse, one especially popular context is games. Producing and consuming live-streamed content is a growing trend attracting many people today. One design implication de- rived from these findings is that, rather than presenting as much information to the spectator as possible, it is more important for the stakeholders to be able to decide how and when they uncover that information. We make three contributions us- ing this data: i) we find nine personas in the data that tell us who the spectators are and why they spectate ii) we strive to understand how different stakeholders, like commenta- tors, players, crowds, and game designers, affect the specta- tor experience and iii) we infer from the spectators' expres- sions what makes the game entertaining to watch, forming a theory of distinct types of information asymmetry that cre- ate suspense for the spectator. We have collected over a hundred stories of the Starcraft spectator from online sources, aiming for as di- verse a group as possible. Our study focuses on Starcraft, a popular real-time strategy game with millions of spectators and high level tournament play. In this paper, we focus on the spectator, who is emerging as an important stakeholder in video games. How- ever, video game spectating is also a popular activity, boosted by the rise of online video sites and major gaming tournaments. Video games are primarily designed for the players.
