AI in games has long been geared towards improving computer-controlled opponents. Will it soon create diverse characters we can talk to instead of just shoot?
In May, as part of an otherwise unremarkable corporate strategy meeting, Sony CEO Kenichiro Yoshida made an interesting announcement. The company’s artificial intelligence research division, Sony AI, would be collaborating with PlayStation developers to create intelligent computer-controlled characters. “By leveraging reinforcement learning,” he wrote, “we are developing game AI agents that can be a player’s in-game opponent or collaboration partner.” Reinforcement learning is an area of machine learning in which an AI effectively teaches itself how to act through trial and error. In short, these characters will mimic human players. To some extent, they will think.
This is just the latest example of AI’s evolving and expanding role in video game development. As open world games become more complex and ambitious, with hundreds of characters and multiple intertwined narratives, developers are having to build systems capable of generating intelligent, reactive, creative characters and emergent side quests.
