Paper Information

• Subject Area: Video Game Design and Player Experience
• Keywords: Video games, reward mechanisms, random rewards, player experience, probabilistic rewards, game design, adaptability, visual presentation, sound effects, game fairness

Research Background and Issues

• Identified Problems or Challenges:

  • Random Reward Mechanisms (RRMs) are a significant component of many modern video games. While they enhance user experience, they are also controversial, raising concerns such as potential gambling characteristics, hindrance to game progression, and negative emotional responses.
  • Academic research on RRMs is limited, particularly regarding how users interact with these systems and how they influence player experience.

• Importance of the Issue:

  • Understanding how to optimize RRMs to enhance players' emotional experiences and game engagement is crucial, especially as game design increasingly emphasizes diversity, emotional depth, and visual expression.
  • The negative impacts of RRMs (e.g., compelling players to spend excessive time or money) require careful design to avoid harming player experience.

• Research Motivation and Related Work:

  • Existing research on video game reward design primarily focuses on reward types and effects, with limited attention to the unique design characteristics and emotional impacts of random rewards.
  • Uncertainty and unpredictability have been recognized as key experiential factors in games, significantly influencing player emotions and behaviors.
  • This study aims to fill this gap by exploring best practices for random reward design and their effects on player emotions and behaviors.

Proposed Solution

• Proposed Methods or Solutions:

  • The authors developed a classification system for RRMs based on design features through video game analysis and interview studies.
  • They conducted an in-depth investigation into how players interact with various types of RRMs, examining the impact of design elements such as sound, visuals, and reward rarity on emotional experiences.
  • Player feedback on randomness, reward acquisition conditions, and reward presentation methods was analyzed to formulate design recommendations.

• Innovative Contributions:

  • A nine-dimensional RRM classification system was proposed, providing a detailed framework for designing random rewards.
  • The study linked the emotional design of RRMs with core gameplay, reward acquisition conditions, and presentation effects, establishing a systematic research approach.
  • It highlighted the role of sound and visual effects ("juiciness") in enhancing players' emotional engagement and analyzed the potential impact of reward rarity on player experience.

• Implementation Steps:

  • Video analysis of 35 RRMs from 28 games was conducted, documenting design features related to reward experiences.
  • Semi-structured interviews with 14 players were carried out to gather subjective user experience data.
  • Based on preliminary analysis, a set of design recommendations was developed to optimize player experience with random reward mechanisms.

Research Outcomes

• Specific Results:

  • A nine-dimensional RRM classification system was developed, encompassing game type, reward value, trigger conditions, reward frequency, visual and sound effects, among others.
  • Positive and negative impacts of RRMs on player experience were identified, such as the freshness and unpredictability introduced by randomness, as well as dissatisfaction with "undesirable rewards."
  • Players exhibited clear emotional preferences for reward rarity and visual presentation, which influenced their perception of game rewards.
  • Players expressed negative attitudes toward RRMs triggered by monetary conditions, citing their repetitiveness as a cause of distraction and emotional disengagement.

• Advantages Compared to Existing Solutions:

  • The study integrated multiple aspects of visual, auditory, and player experience considerations, forming comprehensive recommendations for entertainment and emotional optimization.
  • It offered new perspectives on balancing randomness in RRMs with the relationship between skill and luck.

• Experimental or Evaluation Results:

  • Thematic analysis of interview participants' emotional experiences with RRMs identified trigger conditions, rarity visualization, and reward effects as key factors.
  • Players shared consistent expectations for high-value rewards and their presentation, while expressing lower expectations for simple, low-cost rewards.

• Limitations and Future Directions:

  • The study sample primarily consisted of young male participants, lacking diversity in age and gender.
  • Game selection was based on limited external criteria (e.g., player count and revenue), potentially excluding certain RRM design characteristics.
  • Future research could involve broader user testing and validate these recommendations through practical design implementations.

Conclusion

• Core Findings:
  • This study revealed the multifaceted impact of RRMs on player experience and provided optimization recommendations for game designers through preliminary classification and emotional analysis.
  • It also offered a practical design framework for developing emotionally meaningful and player-friendly random reward mechanisms.
