This document discusses categorizing narrative devices in digital games to promote education and professional understanding. It defines key terms like narrative, nature, intent, space, and approach. Regarding nature, narratives can be explicit or implicit. Explicit narratives directly state information, while implicit narratives express information indirectly. The document examines pros and cons of explicit narratives, and how they are commonly used in AAA games for clarity but can overwhelm players. Implicit narratives allow indirect interpretation and are common in indie games. The document proposes a framework for analyzing and discussing narrative devices using these categories.
