This document summarizes a study on communication strategies used in online team-based games. It finds that players use a scale of politeness from neutral to mildly or highly impolite remarks when communicating with teammates. Neutral remarks include imperatives and explanations, while mildly impolite remarks add elements like using all caps. Highly impolite remarks involve name-calling and flaming language. Interviews reveal different player motivations, from winning to having fun by trolling or raging. The study has implications for education, therapy, and gaming companies' customer satisfaction efforts.
