SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps creators who feel stuck with vague or unformed game ideas by guiding them through a collaborative, studio-style ideation process that produces a complete, written game concept.

Core Features & Use Cases

  • Guided concept discovery and validation: Uses interactive questioning to capture player emotional anchors, taste profile, and practical constraints, then synthesizes them into a Creative Brief.
  • Structured multi-concept ideation: Generates three distinct, directionally different game concepts (including MDA-based aesthetic analysis) and captures the user’s selection or combination.
  • Core loop and pillar definition: Builds the 30-second, 5-minute, session, and progression loops, then collaboratively defines 3–5 pillars and 3+ anti-pillars with design tests, followed by optional director gates to refine pillars and visual direction.
  • Player type and feasibility grounding: Validates audience fit using Bartle taxonomy and motivation models, then gathers scope/constraints (platform, engine preference, risks) to produce scoped, production-ready next steps.
  • Writes or updates the GDD artifact: Produces or revises design/gdd/game-concept.md using the project template and secures explicit write approval from the user.

FAQPage Schema
How do I structure a raw game idea into a game concept document?▼

To structure a raw game idea into a game concept document, use an interactive ideation process that defines player emotions, generates multiple concepts, designs core loops, and writes the finalized output to a GDD markdown file.

What is the best way to define core loops and design pillars for game ideation?▼

Defining core loops and design pillars for game ideation involves collaboratively building 30-second, 5-minute, and session loops, then establishing 3-5 pillars with design tests and refining them through optional director gates.

How do I validate player psychology and audience fit during GDD drafting?▼

To validate player psychology and audience fit during GDD drafting, apply the Bartle taxonomy and motivation models to ensure the scoped game concept aligns with the target audience's emotional anchors.

Can I draft a game concept from scratch with just a genre hint?▼

Yes, you can draft a game concept from scratch by providing a genre hint and enabling a lean review mode, which collaboratively guides the ideation process and captures practical constraints like platform and engine preferences.

Does scope feasibility affect the final game concept document?▼

Scope feasibility directly impacts the final game concept document by gathering technical constraints, assessing risks, and producing scoped, production-ready next steps before writing the approved markdown artifact.
