Masahiro Sakurai discussed generative AI and the demands of game development at the Famitsu 40th Anniversary Festival in Akihabara, Tokyo, on November 7, 2026.
The Kirby and Super Smash Bros. creator appeared at a stage event celebrating Masahiro Sakurai’s Thoughts on Games: Final, a collection of his columns published on November 6.
Why a game idea needs more than a prompt
Sakurai argued that design problems involve context that is difficult to capture fully in prompts. Leaving out those details can produce poor results, because a concept has to work within the practical limits of production.
He identified several conditions that shape whether an idea can become a game:
- Schedule: Can the work be completed by a fixed deadline?
- Staffing: Can the team carry out the proposed idea?
- Cost: Does the concept fit the production budget?
For graphics, Sakurai said generative AI must not become a means of exploitation. He also argued that developers can currently create material more quickly themselves than by relying on the technology.
Kirby Air Riders production demands
The workload behind Kirby Air Riders
Sakurai said Kirby Air Riders required ten times the workload of Kirby Air Ride. His comparison put a concrete production example behind his description of modern game development as far too demanding.
Sales alone do not resolve those pressures. He pointed to titles that still operate at a loss despite selling millions of copies, connecting the discussion of development tools to the difficulty of covering production costs.
Sakurai left future adoption open. He described the question of where and how to use generative AI as complex and said he was taking a cautious approach.
