# Game Design Document

Before generating the full game, AI creates a structured Game Design Document, also known as a GDD.

The GDD helps define the game before the build process starts.

### What the GDD Includes

A GDD may include:

* Game title
* Genre
* Core gameplay loop
* Player objective
* Controls
* Game rules
* Scoring system
* Difficulty progression
* Level structure
* Art direction
* Asset requirements
* IAP opportunities
* Export readiness

### Why the GDD Matters

The GDD helps users review the game direction before AI continues to full generation.

This reduces the risk of generating a game that does not match the user’s idea.

### Reviewing the GDD

After the GDD is created, users can review it and decide whether to continue.

If the GDD looks correct, the user can approve it.

If the GDD needs changes, the user can edit the prompt or request a revision.
