The definitive version was published in CHI PLAY '15 Proceedings of the 2015 Annual Symposium on Computer-Human Interaction in Play, https://doi.org/10.1145/2793107.2810312Analyzing the social con¬text present in a gameplay environment and its effect on player experience can provide insights informing the design and social value of games. We investigate the influence of social condition (cooperative or competitive play with a human player versus computer-controlled character) on player experience. The study controlled for co-presence by ensuring that another individual attending to the same stimulus was present in all conditions. Although physiological measures were not significant, subjective measures of arousal and pleasure were significantly different under varying conditions.enCo-located playComputer gamesHuman-centered computingInteractive gamesMassively multiplayer online gamesMultiplayerPhysiological methodsSingle player video gamesConference Paper
