PART II — The Non-Player Character: A Cultural and Technical History

Part II traces the non-player character across both cultural and technical dimensions, moving from foundational questions about what NPCs are and why they matter, through a decade-by-decade history (from early arcade titles like Space Invaders up through the 2010s), into the complicated emotional and social relationship players have with NPCs—covering affection, frustration, hatred, and the internet-culture phenomenon of "NPC" memes and roleplay. It then turns to the technical and forward-looking side, examining how modern AI and large language models (including GPT-4) are reshaping NPC dialogue and behavior alongside their limitations, and closes with the practical craft of NPC creation: design principles, ethics, pathfinding, navigation, and animation techniques (including Unity-specific tools like NavMesh and Mecanim).
