Machine Learning and Neural Networks (2000s-Present) – In the 21st century, machine learning and neural networks revolutionized AI in gaming. Game developers began using these technologies to create adaptive, learning AI systems. “F.E.A.R.” (2005) introduced advanced enemy AI that employed neural networks to adapt to player tactics. Open-world games like “Grand Theft Auto V” (2013) showcased AI-driven NPCs with complex behavior patterns. Deep reinforcement learning (DRL) has enabled AI agents to master complex games like “Go” and “Dota 2.”
