SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill prevents scope creep and wasted effort by clearly defining the minimum viable artifact needed to test a core design hypothesis, ensuring focus on validation rather than over-building.

Core Features & Use Cases

  • Hypothesis Testing: Clearly articulates the core assumption a prototype aims to validate.
  • Scope Definition: Differentiates between what must be built, what can be faked, and the required fidelity for each element.
  • Build-vs-Fake Decisions: Provides a framework for deciding which game systems are essential for the prototype and which can be simulated.
  • Use Case: Before starting development on a new game mechanic, use this skill to define exactly what needs to be functional to test if the mechanic is fun, and what can be represented with placeholder art or simplified logic.

Quick Start

Use the prototype-scope-definer skill to define the scope for a paper prototype testing a new card-based combat system.

FAQPage Schema
How do I define the minimum viable prototype scope for a new game mechanic?

To define the minimum viable prototype scope, you must articulate the core design hypothesis and establish strict success criteria. This process differentiates essential functional elements from placeholder art or simplified logic to validate if a mechanic is fun.

What is the build-vs-fake framework in game prototype development?

The build-vs-fake framework is a scope definition method for game prototypes that dictates which systems must be fully built to test a hypothesis and which can be simulated. It focuses development resources on validating the riskiest assumptions.

How do I prevent scope creep when testing a card-based combat system?

Prevent scope creep by using a paper prototype to define the exact minimum buildable artifact needed to test the combat hypothesis. This approach prioritizes validation of core mechanics over building high aesthetic fidelity or unnecessary systems.

Can I use prototype scope definition for tabletop and digital games?

Yes, prototype scope definition applies to digital, tabletop, or hybrid game formats. It guides decisions on required aesthetic fidelity and build-vs-fake choices across any medium to ensure the core design hypothesis is effectively tested.

When do I need to define a minimum viable prototype artifact?

You need to define a minimum viable prototype artifact before starting development on a new game mechanic or system. It prevents wasted effort by ensuring you only build what is strictly necessary to test riskiest assumptions and validate the core design.

What is the difference between prototype aesthetic fidelity and functional scope?

Aesthetic fidelity dictates the visual polish of prototype elements, while functional scope defines the actual playable logic. Defining both ensures you only build essential mechanics while faking non-critical visual or systemic elements to test the core hypothesis.
