Deceptive design patterns in digital games often prioritize developer interests at the expense of player well-being by manipulating behavior in potentially harmful ways. While the concept of Radiant Game Design Patterns (RPs) was introduced as a positive alternative to counteract deceptive patterns in games, its initial theoretical framing presented challenges for consistent practical application and operationalization. This paper addresses this gap by proposing two core contributions to advance ethical game design. First, we provide a refined definition of Radiant Patterns, grounded in Self-Determination Theory (SDT), which emphasizes ensuring that foundational player well-being is not significantly compromised by avoiding a decrease in players’ autonomy, competence, and relatedness. Second, we present a detailed documentation structure—a practical template—for defining, instantiating, and sharing RPs that adhere to this refined definition. The application of this definition and structure is illustrated through an in-depth example of an RP. By providing these tools for operationalization, this work aims to equip the Human-Computer Interaction (HCI) community and game developers with a systematic way to collaboratively identify, develop, empirically validate, and implement ethical alternatives to deceptive patterns.
