Digital games offer rich media content and engaging action, accessible individually or in groups collaborating or competing against each other. This makes them promising for use as stimulus in research settings. This paper examines the advantages and challenges of using games in experimental research with particular focus on strict stimulus control through the following four areas: (1) matching and regulating task type, (2) data segmentation and event coding, (3) compatibility between participants and (4) planning and conducting data collection. This contribution provides a breakdown of the steps necessary for using a digital game in experimental studies, along with a checklist for researchers illustrating variables that potentially affect the reliability and validity of experiments. We also offer a practical study example. Ideally, the identification of the methodological and practical considerations of employing games in empirical research will also provide useful in interpreting and evaluating experimental work utilizing games as stimulus.

This paper reviews the psychophysiological method in game research. The use of psychophysiological measurements provides an objective, continuous, real-time, non-invasive, precise, and sensitive way to assess the game experience, but for best results it requires carefully controlled experiments, large participant samples and specialized equipment. We briefly explain the theory behind the method and present the most useful measures. We review previous studies that have used psychophysiological measures in game research, and provide future directions.
