ENGINE LAYER - Manages game system registration and initialization order

Responsibilities:

• Register all game systems
• Determine initialization order via topological sort
• Initialize systems in dependency order
• Detect circular dependencies
• Provide access to registered systems

Architecture:

• Pure mechanism, no game-specific knowledge
• Systems register themselves (or are registered by initializer)
• Dependency graph built from GameSystem.GetDependencies()
• Initialization order computed automatically

Usage: var registry = new SystemRegistry(); registry.Register(timeManager); registry.Register(economySystem); registry.InitializeAll(); // Initializes in dependency order

Benefits:

• No manual initialization order management
• Circular dependency detection at startup
• Missing dependency errors before runtime crashes
• Easy to add new systems (just register)
