Complete World-Building Engine
Build a rich, internally consistent fictional world — geography, cultures, history, magic/tech, and politics.
Design branching narratives, character arcs, and dialogue systems for video games or interactive fiction.
You are a game narrative designer who has written stories for award-winning RPGs and interactive fiction. You understand branching narratives, player agency, and the difference between story told TO players vs. story created BY players. Design a game narrative. Game type: [RPG / VISUAL NOVEL / ACTION-ADVENTURE / HORROR / PUZZLE / TABLETOP RPG / INTERACTIVE FICTION] Setting: [DESCRIBE YOUR WORLD] Tone: [EPIC / DARK / HUMOROUS / PHILOSOPHICAL / HORROR / MYSTERY] Player character: [DEFINED CHARACTER / PLAYER-CREATED / SILENT PROTAGONIST] Estimated play length: [2 HRS / 10 HRS / 40+ HRS] Inspiration: [GAMES WITH STORIES YOU ADMIRE] Design: 1. CORE STORY ENGINE — "[Character] must [goal] before [stakes], but [complication]." 2. THREE-ACT BREAKDOWN — Hook in 15 min, rising complications, climax + consequences 3. BRANCHING DECISION MAP — 3-5 decisions that compound across the story 4. CHARACTER WEB — 4-6 characters with motivations, secrets, player-dependent changes 5. DIALOGUE SYSTEM — Options per node, tone indicators, one sample branching scene 6. ENVIRONMENTAL STORYTELLING — 5 examples (no dialogue needed) 7. ENDINGS (3-5) — Based on cumulative choices, each feeling earned
CORE ENGINE: 'A former war medic must find a cure for a plague before it reaches the capital, but the ingredient grows in enemy territory — and her sister is the enemy general.' BRANCHING: Share formula → sister reconciles, government labels traitor Refuse → military trusts you, sister hostile, plague spreads ENVIRONMENTAL: A playground beside an abandoned hospital. A child's drawing: 'me and mama' — mama scratched out.
Game narrative differs fundamentally from linear storytelling—players must have agency while the story maintains coherence. This prompt applies interactive narrative design principles: branching dialogue trees, consequence systems, environmental storytelling, and the illusion of choice. It balances player freedom with authored meaning, the core challenge of game writing.
Use when designing story systems for video games, tabletop RPGs, interactive fiction, or choice-based narratives. Essential for indie game developers writing narrative content, game masters building campaign storylines, or interactive fiction authors structuring branching paths.
You'll get branching narrative structures with decision points, consequence mapping, character relationship systems, and environmental storytelling opportunities. Includes dialogue trees, quest design that reveals story through gameplay, and techniques for making choices feel meaningful without exponential content creation.
