Capcom Emphasizes That Generative AI Will Complement, Not Replace, Human Creativity in the RE Engine

On October 2, Capcom hosted an open conference for engineers and industry professionals, revealing its vision for the future of the RE Engine. The discussion included insights on how the company plans to integrate AI into its development processes while also outlining areas where it will refrain from using the technology as the gaming landscape evolves.

For nearly a decade, Capcom has relied on its proprietary RE Engine across most of its projects. This engine has been fine-tuned to facilitate shared knowledge among development teams and to adapt projects seamlessly to various hardware, from high-end PCs to the Nintendo Switch. Many believe this technology has played a crucial role in the company’s recent resurgence. During the conference, Capcom representatives shared their thoughts on the engine’s ongoing evolution and the lessons learned throughout its development.

A report from an outlet highlighted that the RE Engine’s continued advancement is part of the REX Initiative (RE neXt engine), first introduced in 2023. This initiative focuses on five key objectives, including simplifying complex code into more manageable rules for faster processing (RE:Dox) and creating more efficient internal reports to identify and rectify coding errors (RE:Log). While these improvements may not be visible to players, they are essential for enhancing the engine’s performance across diverse hardware.

Capcom emphasized that part of the RE Engine’s evolution aims to create an “engine for the AI generation,” enabling collaboration between developers and AI. Earlier this year, the company reassured fans that its games would not feature AI-generated assets, clarifying that its AI initiatives are geared toward streamlining the development process.

As part of this initiative, Capcom has made the RE:Dox and RE:Log tools available as open-source resources on a programming platform. By doing so, the company hopes to allow AI programs to learn how these tools operate. The goal is for AI to analyze human-created code at Capcom and assist in conducting internal playtests, identifying and fixing bugs.

One slide from the presentation indicated that these new AI agents would be capable of playing game builds, logging issues, analyzing data, and detecting visual and gameplay bugs, as well as performance-related problems. They would then suggest fixes for human developers to implement.

This approach is not entirely new; several companies have been exploring similar concepts for years, even before generative AI became a hot topic in the industry. For instance, a notable discussion on a related concept took place at the CEDEC conference in 2024.

Capcom reiterated that its use of AI is intended solely to reduce the burden of repetitive tasks on human developers, allowing them to concentrate on the creative aspects of game development. “AI is not a replacement for humans,” the company affirmed during the conference.
