Elves and Argonians clipping through walls and stepping through tables, blacksmiths who won’t acknowledge your existence until you take single step to the left, Draugers that drop into rag-doll seizures the moment you put an arrow through their eye — Bethesda’s Elder Scrolls long-running RPG series is beloved for many reasons, the realism of their non-playable characters (NPCs) is not among them.

It’s all thanks to the emergence of generative chatbots that are helping game developers craft more lifelike, realistic characters and in-game action.

“Game AI is seldom about any deep intelligence but rather about the illusion of intelligence,” Steve Rabin, Principal Software Engineer at Electronic Arts , wrote in the 2017 essay, The Illusion of Intelligence. “Often we are trying to create believable human behavior, but the actual intelligence that we are able to program is fairly constrained and painfully brittle.”

Just as with other forms of media, video games require the player to suspend their disbelief for the illusions to work. That’s not a particularly big ask given the fundamentally interactive nature of gaming, “Players are incredibly forgiving as long as the virtual humans do not make any glaring mistakes,” Rabin continued. “Players simply need the right clues and suggestions for them to share and fully participate in the deception.”

Take Space Invaders and Pac-Mac, for example. In Space Invaders, the falling enemies remained steadfast on their zig-zag path towards Earth’s annihilation, regardless of the player’s actions, with the only change coming as a speed
