Catly Creator Says Game Has No Generative AI, No Blockchain, and No NFTs – IGN

The spokesperson confirmed to IGN that Catly is being made in Unreal Engine 5, and said the developer uses “various software” to produce hyperrealistic fur and hair.

Assertions that Catly was using generative AI technology began to circulate almost immediately after its trailer debuted at The Game Awards last week. The trailer itself featured hyperrealistic cats with brightly colored fur and features bounding around a fantasy playspace and interacting with a human wearing various detailed, high fashion outfits. The art style present was flagged by many critics as reminiscent of the hyperrealistic style often produced by generative AI. That said, Catly’s statement is consistent with the current reality that game trailers of this quality are not within the reach of current generative AI technology without significant, obvious artifacting and other issues.

However, others pointed out that while the trailer may be legit, the other aspects of Catly’s promotion are still giving some off vibes. For instance, the game’s Steam description awkwardly reads, “A Cat Open World, with Beautiful Cats. Hyperrealism, Actions, Cuddle, Speed, Islands, Fashion, Dreams, Snow, Robots, Plants — all with and via Cats.”

And a few of the game’s promotional art pieces had odd details similar to AI artifacting, such as the odd paws and nose of this cat:

Others unearthed more images from the official Catly website that have since been removed, but which appear to raise even more questions about their veracity.

Update 5:57pm: A previous version of this story claimed the website had been down all weekend, but the URL for the official website provided to IGN was incorrect, and the website has remained live.

Original story continues below:

While SuperAuthenti confirmed to me that it did not use generative AI in either the trailer or the game itself, it did not respond to my question about its promotional images on Steam or on its website.

As for web3, speculation of the game’s ties to the technology surfaced as individuals unearthed the studio co-founder, Kevin Yeung’s, ties to other blockchain games. Additionally, the game’s Steam page features a glowing quote from League of Legends and Arcane producer Thomas Vu, who himself is a prominent web3 investor. However, it also contained a quote from Hearthstone and Marvel Snap creator Ben Brode, who has taken to Bluesky to say that he’s heard nothing about either AI generation or web3 involved in Catly, and that his interest is sincere. “I saw 20 [minutes] or so of gameplay footage a few months back and thought it looked cool so they asked me for a quote,” he wrote.

For now, it does seem that SuperAuthenti is telling the truth about the Catly trailer at The Game Awards, though the question of whether or not, or how much, generative AI has been used in Catly’s overall development and promotion remains to be seen. Generative AI is becoming an increasingly popular tool for game companies, too. Call of Duty reportedly sold an “AI-generated cosmetic” for Call of Duty: Modern Warfare 3 in late 2023, and fans accused Activision of using generative AI again for a loading screen this year. EA said in September that AI was “the very core” of its business.

Unfortunately, as the technology becomes both more prevalent and more complex, it seems likely it will become increasingly difficult to tell the difference between AI-generated and human-crafted work. In Catly’s case, we’ll have to wait for 2025 to find out more about what exactly is behind those hauntingly rainbow cat eyes from the trailer.
