Artificial intelligence (AI) is intelligence exhibited by software or machines rather than humans. In video games, AI is used to simulate human-like behaviors and actions, especially for non-playable characters to make open world games feel more populated. The interactions between players and AI-controlled characters aim to make games feel more alive and immersive. In the future, AI in games could handle more characters on screen simultaneously and act more strategically and human-like by adapting to different situations.
