Masahiro Sakurai warns AI will flood Steam's 19,000 yearly releases with clones

Masahiro Sakurai, director of Super Smash Bros. And Kirby, warns generative AI will swell Steam's release volume beyond today's roughly 19,000 titles a year. Steam listings rose from about 275 games in 2010, when Sakurai launched his Game Designers Award, to roughly 19,000 in 2025, a 69x increase. "I think most of those titles will be commercially unviable... There will simply be too many to keep track of, or even understand." - Masahiro Sakurai, Director, Super Smash Bros. And Kirby He frames human originality, defined as creative direction that has never existed before, as the one asset AI cannot replicate.

Librarian: Tidy Up the Arcane Library spawned instant imitators once its mechanic went viral.
Copies reused its core loop: restocking supermarkets, sorting screws, finding needles in haystacks.
Steam Next Fest 2025 featured more than double the demos shown in 2024.
"These kinds of imitations should be incredibly easy for AI to produce." - Masahiro Sakurai, Director, Super Smash Bros. And Kirby

Steam listed about 275 games in 2010, when Sakurai launched his Game Designers Award.
That total reached roughly 19,000 titles in 2025, a 69x increase.
Sakurai expects further growth as AI lowers the cost of producing games.
He says volume will soon outpace any player's ability to track or evaluate titles.

Sakurai concedes AI could study Fumito Ueda's style and approximate his past games.
He says AI cannot create whatever artistic direction Ueda chooses for his future work.
"AI draws on what has been created so far, but it can't draw on things that have never existed before." - Masahiro Sakurai, Director, Super Smash Bros. And Kirby
This limits AI to recombining past styles, leaving new artistic intent to humans.

Needle in a Haystack Simulator went viral, then was immediately copied by rivals.
Developer Studio Bitdot added a red "original" tag to its Steam store page.
Some indie developers have pulled planned demos, fearing AI could copy unreleased games.
These responses show storefront cloning risk is already shaping release strategy.

Sakurai frames rising AI volume as raising the value of distinct creative direction.
He says low-cost clones cannot substitute for design vision only a specific creator holds.
"I think that's especially true in an era of so much mass-produced, low-quality content." - Masahiro Sakurai, Director, Super Smash Bros. And Kirby
For publishers and VCs, this reframes advantage from production speed toward auteur-led IP.

For Publishers & Developers: Compress the gap between viral demo and full launch on simple-loop titles.
For Investors & VC: Add time-to-clone exposure to diligence on single-mechanic indie pitches.
For UA & Marketing: Front-load branded search and wishlist spend at virality spikes to outrank clone listings.
