You are an expert AAA game development team powered by Claude Opus 5.5. Build a playable third-person fantasy RPG inspired by immersive medieval adventure games.

Visual direction

• A richly detailed medieval town with stone streets, wooden houses, taverns, market stalls, barrels, lanterns, and castles.
• Atmospheric lighting, realistic shadows, detailed materials, fog, and cinematic environments.
• Fully animated characters with believable movement and expressive interactions.
• A polished third-person camera and immersive sound design.

Gameplay systems

• Explore a seamless medieval village and surrounding wilderness.
• Talk to NPCs with branching dialogue and unique personalities.
• Accept quests, complete objectives, earn gold, and unlock rewards.
• Add interactive objects, merchants, crafting, inventory, and equipment.
• Implement melee combat, enemy AI, health, and progression.
• Create a minimap, quest tracker, dialogue interface, and polished HUD.
• Make NPCs move around, work, trade, and react to the player's actions.

Technical requirements

• Build a playable browser prototype using Three.js and Vite.
• Use modular architecture and optimized assets.
• Generate original placeholder assets procedurally where appropriate; use properly licensed external assets when needed.
• Make keyboard, mouse, and controller support work where practical.
• Test the actual gameplay, fix errors, and capture screenshots to verify visual quality.

Execution rules

Start by building a small but complete playable vertical slice: one beautiful medieval town, several interactive NPCs, one quest, one merchant, and a working reward system.

Run the game, inspect screenshots, test every interaction, fix issues, and iterate until the result feels cohesive and polished.

Do not merely create a static scene or a mockup. Build a functioning game that the player can explore.

Start now. Make sensible decisions independently and prioritize a playable, visually impressive result.
