1. Introduction to Game Outcomes and Player Experience

Understanding how players interact with games involves recognizing the subtle interplay between **karma** and **gravity**—two forces that shape not only the mechanics but the very meaning of every choice. At the core, inertia—both physical and metaphorical—represents the resistance to change, mirroring the weight of past decisions that pull players along predictable paths. When a player stares at a branching path, inertia often keeps them grounded in familiar choices, much like how gravitational pull anchors objects in space.

2. Momentum as Narrative Weight: The Accumulation of Player Decisions

Just as momentum builds in physics, **momentum in games accumulates through player decisions**, creating narrative weight that influences future options. Every action—whether a moral choice, a combat style, or a dialogue—adds inertia to the player’s journey. Over time, these decisions create a **cumulative inertia**, where each prior choice shapes the available paths, much like how a rolling ball gains force and resists reversal.

• Past choices build **narrative inertia**, making certain outcomes feel inevitable.
• Cumulative consequences act as a **gravity-like force**, gently pulling players toward similar future decisions.
• This dynamic reinforces player agency by deepening immersion—choices don’t exist in isolation, but in a chain of cause and effect.

3. Temporal Inertia: The Lingering Effects of Past Actions on Current Choices

Temporal inertia refers to how **memory and consequence delay or shape present decisions**, much like gravitational pull persists long after a force has acted. When players reflect on earlier actions—such as betraying a companion or forging alliances—their past behavior
