Artificial Intelligence (AI) in games has evolved from predictable enemies to dynamic systems. Today, AI drives more than just enemy behavior—it enhances realism in NPC interactions, procedural content generation, and adaptive difficulty. Games like Shadow of Mordor introduced the Nemesis system, where enemies remember past encounters. In RPGs, AI influences character decisions and dialogue. AI also powers behind-the-scenes features like matchmaking and voice recognition. Developers are experimenting with machine learning for smarter NPCs and creating more lifelike behaviors. As AI technology continues to grow, it will redefine how games are built, played, and experienced—making virtual worlds feel even more alive.
