The complexity of video games is growing rapidly, with new game genres and game mechanics emerging. To keep pace with this, a broadly defined and widely applicable framework is needed to increase our understanding of how video game rewards impact the player experience. However, very few such frameworks exist, and those that do tend to be based on their authors' experience with video games. This thesis aimed to create a new typology for examining video game rewards in a meaningful and applicable way. A mixed-methods approach was used to iteratively develop a new video game reward typology. First, existing methods for classifying video game rewards were identified, trialled and revised. A set of focus groups was then conducted to explore the applicability of the existing and revised video game reward typologies to video games.Two card-sorting activities were then undertaken to test the applicability of the existing and revised video game reward typologies. This indicated that the revised video game reward typology was a more useful tool for classifying video game rewards.A purpose-built video game was then developed to determine the impact of eight video game reward conditions on the player experience in an online experiment. While we did not find a distinct difference between individual reward types, we did find that the diversity of video game reward types present in the experiment affected enjoymentbeing exposed to the full range of video game reward types led to greater enjoyment than exposure to only one individual reward type or to no rewards. This confirms that video game developers should aim to include a breadth of video game rewards in their game designs to maximise player enjoyment. Beyond this, we also found that reward responsiveness plays an important role in facilitating enjoyment-participants with higher levels of trait reward responsiveness enjoyed all versions of the game more than participants with lower levels of trait reward responsiveness. This result indicates that player experience investigations should consider player traits to gain a holistic understanding of how relevant constructs impact the player experience.This thesis has resulted in the development of a video game reward typology that can be used to accelerate understanding of video game rewards; it has also contributed to knowledge of how video game reward types impact the player experience. The contributions of this work thus have implications for both video game researchers and video game development practitioners.
