Tale Engine is a narrative-focused RPG engine developed from scratch.

The engine is being built entirely using ChatGPT 5.2. All engine architecture, systems, DSL design, and source code are generated by AI, with a human developer directing, reviewing, testing, and committing the results.

This project intentionally explores AI as the primary code author, not merely as an assistant.

• A from-scratch RPG engine (not based on Unity, Godot, or Unreal)
• Focused on narrative, choices, and consequences
• Uses a custom, human-readable DSL for story content
• Deterministic and validation-driven
• Desktop tooling only (no web editor)

• ChatGPT 5.2 writes the code
• The human developer:
  • defines goals
  • evaluates design decisions
  • runs and tests the code
  • performs all commits

This repository reflects an explicit human–AI development workflow.

Early development.

• Engine skeleton and tooling bootstrap completed
• DSL parsing and validation in progress

See docs/engine_roadmap.txt for planned milestones.
