description: Understanding the differences between BMGD and BMM
|
|

|
|
|
|
|
|
BMGD (BMad Game Development) extends BMM (BMad Method) with game-specific capabilities. This page explains the key differences.

## Agent Differences
|
|
|
|
### BMM Agents
|
|
- PM (Product Manager)
|
|
- Architect
|
|
- DEV (Developer)
|
|
- SM (Scrum Master)
|
|
- TEA (Test Architect)
|
|
- Quick Flow Solo Dev
|
|
|
|
### BMGD Agents
|
|
- Game Designer
|
|
- Game Developer
|
|
- Game Architect
|
|
- Game Scrum Master
|
|
- Game QA
|
|
- Game Solo Dev
|
|
|
|
BMGD agents understand game-specific concepts like:
|
|
- Game mechanics and balance
|
|
- Player psychology
|
|
- Engine-specific patterns
|
|
- Playtesting and QA
|

## Planning Documents
|
|
|
|
### BMM Planning
|
|
- **Product Brief** → **PRD** → **Architecture**
|
|
- Focus: Software requirements, user stories, system design
|
|
|
|
### BMGD Planning
|
|
- **Game Brief** → **GDD** → **Architecture**
|
|
- Focus: Game vision, mechanics, narrative, player experience
|
|
|
|
The GDD (Game Design Document) includes:
|
|
- Core gameplay loop
|
|
- Mechanics and systems
|
|
- Progression and balance
|
|
- Art and audio direction
|
|
- Genre-specific sections
|
|
|

|
|
|
|
## Game Type Templates
|
|
|
|
BMGD includes 24 game type templates that auto-configure GDD sections:
|
|
|
|
- Action, Adventure, Puzzle
|
|
- RPG, Strategy, Simulation
|
|
- Sports, Racing, Fighting
|
|
- Horror, Platformer, Shooter
|
|
- And more...
|
|
|
|
Each template provides:
|
|
- Genre-specific GDD sections
|
|
- Relevant mechanics patterns
|
|
- Testing considerations
|
|
- Common pitfalls to avoid
|
|
|

|
|
|
|
## Narrative Support
|
|
|
|
BMGD includes full narrative workflow for story-driven games:
|
|
|
|
- **Narrative Design** workflow
|
|
- Story structure templates
|
|
- Character development
|
|
- World-building guidelines
|
|
- Dialogue systems
|
|
|
|
BMM has no equivalent for narrative design.

|
## Testing Differences
|
|
|
|
### BMM Testing (TEA)
|
|
- Web-focused (Playwright, Cypress)
|
|
- API testing
|
|
- E2E for web applications
|
|
|
|
### BMGD Testing (Game QA)
|
|
- Engine-specific frameworks (Unity, Unreal, Godot)
|
|
- Gameplay testing
|
|
- Performance profiling
|
|
- Playtest planning
|
|
- Balance validation
|
|

|
|
## Production Workflow
|
|
|
|
BMGD production workflows **inherit from BMM** and add game-specific:
|
|
- Checklists
|
|
- Templates
|
|
- Quality gates
|
|
- Engine-specific considerations
|
|
|
|
This means you get all of BMM's implementation structure plus game-specific enhancements.
