Takaya Imamura, the Nintendo artist associated with several major series, has faced strong online criticism after sharing an experiment involving generative artificial intelligence and game development.
Imamura worked as the graphic designer on Star Fox, designed characters for F-Zero: Climax, supervised Super Smash Bros. Brawl and served as art director for The Legend of Zelda: Majora’s Mask. His background helps explain why a short prototype attracted considerable attention.

An AI-assisted shooter prototype
On September 12, 2026, Imamura shared images of a 3D shooter prototype on X. An automatic translation of his Japanese post described the project as a test of AI-assisted game development.
“I’m currently testing out game development using AI. Bouncing ideas back and forth with the AI brings back the feeling of the days when I used to build games while brainstorming—‘let’s try this, let’s try that’—with a programmer. It really is an amazing era we live in.”
Why the post drew criticism
The response appeared to come largely from Japanese users on X. One reply argued that Imamura should not experiment with AI while the technology is facing intense criticism and overseas boycotts.
The reply also claimed that current AI systems depend on the misappropriation of other people’s data. It warned that using the technology could damage a company’s credibility, pointing to Level-5 as an example, and asked Imamura not to proceed.
The debate touches on concerns familiar across game development: how training data is sourced, how artists’ work is treated and where experimentation ends and commercial production begins. For builders and restorers, those questions sit alongside more practical choices about hardware, software and hands-on design. RETROCADE’s arcade machine buying guide covers a different part of that wider technology conversation.
Imamura explains the experiment
Imamura said he understood the criticism but could not ignore AI given his profession. In a response posted on X, he explained that he is not a programmer and was surprised that AI could help bridge the gap between his ideas and a functioning game.
“I completely understand your point. However, given my profession, AI is something I simply can’t ignore, so I’m experimenting with it as a test. I’m not a programmer, so I’m genuinely amazed by how AI can fill in that gap and actually help me turn my ideas into a working game.”
That wording led some readers to interpret the project as a possible path towards a finished release. Imamura later clarified in a follow-up post that he had never said the prototype would be completed or released.
“It’s incredible… I’m getting slammed this hard just for making a quick game prototype using AI… I never even said a word about finishing or releasing it…”
A wider divide over generative AI
Developers using AI for game projects have faced angry reactions before, but the apparent concentration of criticism among Japanese players adds another dimension to the discussion. Audiences in different regions have not responded to generative AI in games in the same way.
Imamura’s experiment does not establish plans for a commercial game. It does, however, show how quickly even a small prototype can become part of a larger argument about authorship, training data, professional standards and the future of game creation.
