Dragon Quest Co-Creator Yuji Horii Releases a Game He Says Took 30 Minutes With AI

Yuji Horii, the writer and designer who co-created Dragon Quest with Koichi Sugiyama and Akira Toriyama, has released a new game that he says took about half an hour to make. The more notable detail is how it was built. Horii describes the project less as something he coded and designed by hand and more as something he prompted into existence with generative AI.

That framing is what makes the announcement stand out. Horii is tied to one of the most influential role-playing franchises ever made, and Dragon Quest has spent nearly four decades shaping the genre's conventions, from its turn-based combat to its approachable, menu-driven design. Seeing a creator with that background experiment with tools that can generate playable software on demand is a notable moment, even if the game itself is small in scope.

The 30-minute figure comes from Horii himself, and it is hard to judge from the outside how much work sat behind it. Refining prompts, testing the output, and fixing problems after the first draft all take time, and speed claims like this often leave that iteration out. Still, the broader point holds: the barrier to making a simple game keeps falling, and experienced developers are now testing how far it can go.

Reaction across the games industry to AI-generated content has been mixed. Some developers worry about job security and about the craft that gets lost when a project is assembled quickly from prompts. Others see AI mainly as a prototyping shortcut that lets a single person test ideas in an afternoon. Horii's experiment lands squarely in that debate, and how players and studios respond will likely depend on what the game is and how it was presented.
