                - **Dependency Inversion**: High-level modules don't depend on low-level modules
                - **Interface Segregation**: Small, focused interfaces
                - **Single Responsibility**: Each class has one reason to change
                - **Open/Closed**: Open for extension, closed for modification

                **PlayerService**
                - Player management and lifecycle
                - Movement and position tracking
                - Health and experience management
                - Statistics and progression
                
                **ChatService** 
                - Public and private messaging
                - Message history and persistence
                - Command processing
                - Real-time communication
                
                **NPCService**
                - NPC behavior management
                - Interaction handling
                - Personality systems (like Donald's responses)
                - Movement and AI logic
                
                **MCPService**
                - AI agent registration and management
                - MCP protocol implementation
                - External service integration
                - Tool and capability exposure
                
                **PluginService**
                - Plugin discovery and loading
                - Dependency management
                - Hot-reload functionality
                - Event system coordination
                
                ### Service Communication
                - Services communicate through well-defined interfaces
                - Event-driven architecture for loose coupling
                - Centralized coordination through GameEngine
                - Thread-safe operations with proper locking

                - Detailed logging for debugging and monitoring
                - Recovery mechanisms for transient failures

                - Smart caching for frequently accessed data
