Video games have been leveraging artificial intelligence (AI) since the 1950s, but the rapid advancement of generative AI is now opening up new possibilities for the gaming industry. Generative AI refers to the use of artificial intelligence algorithms to create text, images, and audio in response to a prompt. This technology has the potential to revolutionize non-playable characters (NPCs), which are an integral part of video game worlds.
Traditionally, NPCs have followed predetermined behavior patterns, resulting in stilted and unnatural interactions. The introduction of generative AI can change this by enabling developers to create more authentic and unpredictable NPCs. For example, La Forge China, a research and development unit of Ubisoft, has launched Ghostwriter, a text-generating AI tool designed to help writers create diverse and original dialogues for NPCs.
Furthermore, La Forge has also tested a technology that generates more realistic gestures in NPCs based on their speech and mood. By combining generative AI elements like dialogue and animation, it is possible to create fully fleshed-out NPCs with natural behaviors. These advancements in NPC design contribute to more immersive and engaging gameplay experiences.
In addition to improving dialogue and animations of NPCs, some game publishers are using generative AI to make conversations more realistic. Chinese gaming company NetEase uses ChatGPT to generate NPC dialogue in its mobile game “Justice,” while Replica Studios introduced “AI-powered smart NPCs” for Unreal Engine that can read NPC dialogues without requiring human voice actors.
However, there are challenges associated with using AI-generated NPCs. Julian Togelius, an associate professor at New York University who conducts research on AI and games, points out that the risk lies in game designers potentially losing control over the narrative when NPCs generate content autonomously. Maintaining consistency within game worlds becomes vital so that NPCs don’t say something that breaks immersion or disrupts gameplay.
Despite these challenges, generative AI presents exciting opportunities for the gaming industry. Open-world games, such as “Grand Theft Auto” and “Skyrim,” rely on non-linear gameplay and quests. This provides an ideal platform for generative AI to reshape player experiences by creating infinite opportunities, customized cities, landscapes, and interactive elements. By analyzing player data from previous gameplay sessions, generative AI can generate unique storylines and personalized quests like a tailored dungeon master.
Generative AI also has the potential to revolutionize user-generated content (UGC). Game developers can leverage this technology to make the production of UGC easier and increase its quality. Maxis, the developer behind “The Sims,” is optimistic about how generative AI can enhance player customization and create more emergent player experiences.
Moreover, generative AI holds promise for streamlining game development processes. Tools like Ghostwriter or ZooBuilder (a 3D animator that animates animals based on videos) can assist designers in eliminating repetitive tasks, allowing them to focus on more creative aspects of game development. However, it is important to note that generative AI is not meant to replace human game developers but rather empower them with additional creative tools.
While there are ongoing legal and ethical concerns surrounding generative AI in gaming, companies like La Forge are excited about the possibilities this technology brings. Its accessibility can benefit independent game studios by enabling them to produce high-quality games at scale. Future developments in generative AI have the potential to transform video games into even more compelling and immersive experiences.
As Togelius succinctly puts it, “Video games are in for quite a trip in the next decade or two.” The integration of generative AI requires a paradigm shift in game design thinking but promises to elevate the overall gaming experience significantly.
