BMad Game Development (BMGD)

A comprehensive game development toolkit providing specialized agents and workflows for creating games from initial concept through production.

Overview

The BMGD module brings together game-specific development workflows organized around industry-standard development phases:

• Preproduction - Concept development, brainstorming, game brief creation
• Design - Game Design Document (GDD) and narrative design
• Technical - Game architecture and technical specifications
• Production - Sprint-based implementation using BMM workflows

Installation

bmad install bmgd

During installation, you'll be asked to configure:

• Game project name
• Document storage locations
• Development experience level
• Primary target platform

Components

Agents (4)

Game Designer 🎨 Creative vision and game design documentation specialist. Creates compelling GDDs and defines game mechanics.

Game Developer 🕹️ Senior implementation specialist with expertise across Unity, Unreal, and custom engines. Handles gameplay programming, physics, AI, and optimization.

Game Architect 🏗️ Technical systems and infrastructure expert. Designs scalable game architecture and engine-level solutions.

Game Dev Scrum Master 🎯 Sprint orchestrator specialized in game development workflows. Coordinates multi-disciplinary teams and translates GDDs into actionable development stories.

Team Bundle

Team Game Development 🎮 Pre-configured team including Game Designer, Game Developer, and Game Architect for comprehensive game projects.

Workflows

Phase 1: Preproduction

• brainstorm-game - Interactive game concept brainstorming
• game-brief - Create focused game brief document

Phase 2: Design

• gdd - Generate comprehensive Game Design Document
• narrative - Design narrative structure and story elements

Phase 3: Technical

• game-architecture - Define technical architecture (adapted from BMM architecture workflow)

Phase 4: Production

Production workflows are provided by the BMM module and accessible through the Game Dev Scrum Master agent:

• Sprint planning
• Story creation and management
• Epic technical specifications
• Code review and retrospectives

Quick Start

1. Start with Concept Development

Load agent: game-designer
Run workflow: brainstorm-game

2. Create Game Brief

Run workflow: game-brief

3. Develop Game Design Document

Run workflow: gdd

4. Define Technical Architecture

Load agent: game-architect
Run workflow: game-architecture

5. Begin Production Sprints

Load agent: game-scrum-master
Run: *sprint-planning

Configuration

After installation, configure the module in _bmad/bmgd/config.yaml

Key settings:

• game_project_name - Your game's working title
• game_design_docs - Location for GDD and design documents
• game_tech_docs - Location for technical documentation
• game_story_location - Location for development user stories
• game_dev_experience - Your experience level (affects agent communication)
• primary_platform - Target platform (PC, mobile, console, web, multi-platform)

Workflow Integration

BMGD leverages the BMM module for production/implementation workflows. The Game Dev Scrum Master agent provides access to:

• Sprint planning and management
• Story creation from GDD specifications
• Epic technical context generation
• Code review workflows
• Retrospectives and course correction

This separation allows BMGD to focus on game-specific design and architecture while using battle-tested agile implementation workflows.

Example: Creating a 2D Platformer

1. Brainstorm concepts with brainstorm-game workflow
2. Define the vision with game-brief workflow
3. Design mechanics and progression with gdd workflow
4. Craft character arcs and story with narrative workflow
5. Architect technical systems with game-architecture workflow
6. Implement via Game Dev Scrum Master sprint workflows

Development Roadmap

Phase 1: Core Enhancement

• Customize game-architecture workflow for game-specific patterns
• Add game-specific templates (level design, character sheets, etc.)
• Create asset pipeline workflows

Phase 2: Expanded Features

• Add monetization planning workflows
• Create playtesting and feedback workflows
• Develop game balancing tools

Phase 3: Platform Integration

• Add platform-specific deployment workflows
• Create build and release automation
• Develop live ops workflows
