To complete your Lua game development knowledge, you must understand how to design a full engine:

• entity management
• components
• systems
• module lifecycle
• asset management
• scripting pipelines
• performance tuning
• optimization patterns
• debugging & profiling

Lua excels as an engine scripting language due to:

• fast VM
• low memory footprint
• simple integration with C/C++
• natural data-driven design
• coroutine support
• quick iteration
• extensibility

This chapter finalizes the architecture needed for professional, scalable Lua game engines.
