Player decision modeling can provide useful guidance to understand player performance in games. This information is used to increase consideration of player characteristics from the user’s perspective and develop more user-centered video games. This paper presents an initial proposal of a factor such as sound that may be considered when developing games, to see if horror games are facing challenges related to sound aspects of the game. Through related work, experiments, interviews and observations this paper aims to answer how sound in horror-games changes our gameplay experience as well as what impact the absence of sound has on a horror-game. We also present the results of this field study and present some suggestions for future research.
