Greater rewards in videogames lead to more presence, enjoyment and effort.

There is currently limited understanding of whether and how different amounts and diversity of virtual rewards impact on the player experience. A repeated-measures experiment was undertaken in which participants (N = 59) were compared on subjective measures (competence, presence-immersion, tension, effort and enjoyment), as well as psychophysiological measures (electrodermal activity and heart-beat rate), during the play of a videogame with three levels of video game reward (high, medium, low). Effort, enjoyment and presence-immersion significantly varied across conditions such that they were greater when all rewards were present compared to one or both of the other conditions. Heart-beat rate was found to vary across conditions consistent with the explanation that greater rewards lead to greater arousal. Our study suggest a number of advantages to greater amount and diversity of virtual rewards in the context of a casual videogame, with potential application to the design of new gamification systems.
