Artificial intelligence is revolutionizing video games by enhancing non-player characters (NPCs) to exhibit more lifelike and context-aware behaviors, such as reacting to player actions and interacting with each other. AI also enables games to learn from player skills and strategies, dynamically adapting difficulty and generating unique content like maps and quests. This integration aims to create more immersive and personalized gaming experiences, moving beyond static NPC interactions to dynamic, responsive virtual worlds.
