Can AI make video games more immersive? Some studios turn to AI-fueled NPCs for more interaction

AI technology in video games is evolving to create more interactive, responsive, and immersive experiences for players worldwide.

For decades, video games have relied on scripted, stilted interactions with non-player characters to help shepherd gamers in their journeys. But as artificial intelligence technology improves, game studios are experimenting with generative AI to help build environments, assist game writers in crafting NPC dialogue and lend video games the improvisational spontaneity once reserved for table-top role-playing games.

In the multiplayer game “Retail Mage,” players help run a magical furniture store and assist customers in hopes of earning a five-star review. As a salesperson — and wizard — they can pick up and examine items or tell the system what they'd like to do with a product, such as deconstruct chairs for parts or tear a page from a book to write a note to a shopper.

A player’s interactions with the shop and NPCs around them — from gameplay mechanics to content and dialogue creation — are fueled by AI rather than a predetermined script to create more options for chatting and using objects in the shop.

“We believe generative AI can unlock a new kind of gameplay where the world is more responsive and more able to meet players at their creativity and the things that they come up with and the stories they want to tell inside a fantasy setting that we create for them,” said Michael Yichao, cofounder of Jam & Tea Studios, which created “Retail Mage.”

The typical NPC experience often leaves something to be desired. Pre-scripted interactions with someone meant to pass along a quest typically come with a handful of chatting options that lead to the same conclusion: players get the information they need and continue on. Game developers and AI companies say that by using generative AI tech, they aim to create a richer experience that allows for more nuanced relationships with the people and worlds that designers build.

Generative AI could also provide more opportunities for players to go off-script and create their own stories if designers can craft environments that feel more alive and can react to players' choices in real-time.

Tech companies continue to develop AI for games, even as developers debate how, and whether, they’ll use AI in their products. Nvidia created its ACE technologies to bring so-called “digital humans” to life with generative AI. Inworld AI provides developers with a platform for generative NPC behavior and dialogue. Gaming company Ubisoft said last year that it uses Ghostwriter, an in-house AI tool, to help write some NPC dialogue without replacing the video game writer.
