Create Game Story

Interactive, step-by-step game story creation. Guide the user through the entire narrative design process using questions and choices at each stage. Never dump the entire story at once — build it collaboratively.

Process

Phase 1: Genre & Tone

Ask the user to pick (or describe) the game's genre and tone. Present these as choices:

Genre:

• Fantasy (swords, magic, mythical creatures)
• Sci-Fi (space, cyberpunk, post-singularity)
• Horror (survival horror, psychological, cosmic)
• Post-Apocalyptic (wasteland, zombie, nuclear)
• Historical / Realistic (war, mystery, thriller)
• Hybrid (let them combine)

Tone:

• Dark & Serious
• Lighthearted & Comedic
• Epic & Heroic
• Mysterious & Atmospheric
• Player-driven (morally gray choices)

Target audience: Casual, Core Gamer, Narrative-focused

Phase 2: World-Building

Based on genre selection, ask focused questions:

1. Setting — Where does the game take place? Offer 3 setting options tailored to their genre, plus "describe your own"
2. Time period — When? Past, present, future, timeless
3. Scale — Single location, city, continent, planet, multiverse
4. Rules — What makes this world unique? Magic system, technology level, societal structure
5. Conflict — What is the central tension in this world? War, plague, invasion, collapse, mystery

After each answer, reflect back a 2-3 sentence world summary and ask if they want to refine it.

Phase 3: Characters

Build the cast one character at a time:

1. Protagonist — Ask:

   • Name and appearance (brief)
   • Background / origin (offer 3 archetype options + custom)
   • Core motivation (revenge, survival, discovery, redemption, duty)
   • Fatal flaw or internal conflict
   • Starting abilities / skills

2. Antagonist — Ask:

   • Nature (person, faction, force, self)
   • Motivation (why they oppose the protagonist)
   • Connection to protagonist (personal, ideological, coincidental)

3. Supporting cast — Ask if they want 1-3 key NPCs:

   • Role: Mentor, Companion, Rival, Love Interest, Trickster, Guide
   • One defining trait per NPC

Present a character lineup summary after this phase.

Phase 4: Plot Structure

Offer a narrative structure choice:

• Three-Act — Setup, Confrontation, Resolution
• Hero's Journey — Call to adventure through return
• Branching — Multiple paths with diverging outcomes
• Episodic — Self-contained chapters/missions
• Open World — Player-driven with a loose main thread

Then collaboratively build:

1. Inciting incident — What triggers the story? Offer 3 options based on world + characters
2. Act 1 / Setup — First 20% of the game, what does the player experience?
3. Midpoint twist — What changes everything halfway through?
4. Act 2 / Rising action — Escalating stakes, what goes wrong?
5. Climax — The final confrontation or revelation
6. Resolution — How does it end? Offer multiple ending possibilities if branching

Phase 5: Quests & Missions

For each major story beat, generate:

1. Main quests — 5-8 core story missions with:

   • Quest name
   • Objective (1 sentence)
   • Location
   • Key NPCs involved
   • Reward / story unlock

2. Side quests (optional) — Ask if they want 3-5 side quests:

   • Tied to world lore or character backstory
   • Optional but enriching

Phase 6: Dialogue & Lore Samples

If the user wants, generate:

• Opening cinematic / narration (3-5 paragraphs)
• Key dialogue exchange (protagonist meets antagonist)
• 2-3 lore entries (journal entries, codex items, environmental storytelling)
• Item descriptions for key objects

Phase 7: Story Document Output

Compile everything into a structured markdown document:

Rules

• Always ask, never assume. Present 2-4 options at each decision point plus a custom option.
• Summarize after each phase before moving on. Let the user revise.
• Keep it concise. Story beats should be 1-3 sentences. Full prose only in Phase 6.
• Reference the 3d-game-design skill when discussing engine capabilities, physics, or technical feasibility.
• No spoilers upfront. Build the story incrementally so the user experiences the creative process.
• If the user already has a partial story, ask what's done and fill in the gaps.
