FAQ
Generative AI refers to artificial intelligence that generates new content, such as text, images, music, or other data types, based on the input it receives. It is designed to create content at a level that challenges, but does not yet surpass, the Turing test.
Some game developers avoid using generative AI due to concerns about the ethics of AI use, potential copyright issues, and the limitations of AI in truly innovative and creative tasks. For instance, 21% of AAA studios prohibit the use of AI entirely.
According to the Game Developers Conference's State of the Industry Report, nearly half of game developers use generative AI in their studios. Tools like GitHub's Copilot, ChatGPT, and Adobe Generative Fill are popular. However, there is a significant variation in usage based on roles within the company.
Traditional uses of AI in video games include path-finding AI for character movement, finite state machines for managing NPC behavior, decision trees for strategic decision-making, behavior trees for flexible AI behaviors, utility AI for evaluating actions, and steering AI for realistic movement in racing games.
Currently, AI is unlikely to create truly innovative game designs. AI tends to be derivative, building on existing knowledge and data. While AI can suggest new uses and parse data quickly, true innovation in game design still relies heavily on human creativity and experience.
AI can assist in game development by automating processes, summarizing large amounts of text, and providing information quickly, acting as a 'super Google.' However, AI is generally not used for tasks that require deep creativity, such as writing narratives or designing game mechanics.
AI plays a significant role in procedural generation, which is used to create endless content such as terrains, dungeons, and flora in games like Minecraft. This is done using crafted algorithms based on random seeds or predefined rules.
Generative AI is not widely adopted in AAA game studios due to high ethical concerns, potential legal risks, and the substantial cost and complexity of game development. Many developers prefer to rely on human creativity and established AI techniques.
Examples of AI techniques used in popular games include path-finding AI in Doom, finite state machines in Red Dead Redemption 2, decision trees in Age of Empires 4, behavior trees in Halo 2, and scripted AI in Baldur's Gate 3.
Concerns about the use of AI in creative fields include ethical issues, potential copyright infringement, and the risk of AI-generated content being unoriginal or derivative. There are also worries about how AI might impact the creative process and job roles within the industry.
