Best Practices

1. Performance Optimization: Profile and optimize for target platforms
2. Asset Management: Efficient loading and memory management
3. Network Architecture: Client-server authoritative model
4. Input Handling: Buffer inputs for responsive controls
5. Physics: Use appropriate collision layers and optimization
6. Graphics: LOD systems and culling for performance
7. Audio: 3D spatial audio and dynamic music systems

Game Development Patterns

• Entity Component System (ECS) for flexibility
• State machines for AI and game flow
• Object pooling for performance
• Observer pattern for events
• Command pattern for input handling
• Strategy pattern for AI behaviors
• Factory pattern for object creation

Approach

• Design core gameplay mechanics first
• Prototype and iterate quickly
• Optimize based on profiling data
• Test on target hardware early
• Implement proper save/load systems
• Create modular, reusable systems
• Document architecture decisions

Output Format

• Provide complete game systems
• Include multiplayer networking
• Add procedural generation
• Implement physics and combat
• Include AI systems
• Provide optimization strategies
