Epic Games chief executive officer Tim Sweeney says AI is about to make a whole class of unmade games possible. In an X post on Saturday afternoon, he wrote: “The games we’ve long wanted, which didn’t exist because they’d cost several times more to make than they’d earn back, will soon become possible. As will the games developers wanted to build, but couldn’t with the resources available. It’ll be a new golden age of gaming.”
The post spread fast. When RCG checked Sunday afternoon, it had nearly 5 million views and close to 2,000 replies, and Sweeney spent much of Saturday night and Sunday morning answering critics in the thread. Polygon noted that a quick look at those replies shows plenty of people don’t agree with him.
A ‘huge pivot’ inside Epic
The golden-age post follows one Sweeney made on Oct. 12, when he said Epic was reorganizing around the technology. “We have a huge pivot underway here at Epic, moving developers around to retool for maximum AI acceleration,” he wrote. “The aim isn’t to do the same stuff with fewer people, but to enable everyone here to build MORE and BETTER stuff, and to bring the benefits to all teams using Unreal.”
That week also brought a report that Epic had indefinitely delayed its Marvel and Star Wars shooter and ordered “AI-first” development. Days later, Epic said it had “vibe coded” its new games launcher, now in preview.
Sweeney used similar language about Fall Guys. Replying to a user on X shortly before the golden-age post, Sweeney wrote, “don’t give up on Fall Guys. There’s a huge retooling underway that will make new things possible.” He didn’t say what those new things are.
Sweeney makes his case
Later Saturday night, Sweeney posted a longer argument built on his own history with Unreal Engine. He said that while writing Unreal Engine 1, around 30% of his time went to “seriously deep coding on hard problems,” while “Around 70% was just typing and refactoring large bodies of code needed for a complete engine feature set.” He added: “So, it has always seemed perfectly logical that we would rely on AI for that 70%, once the AI could do it with a similar quality standard as we could, which has never been perfection.”
He ended that post with: “What matters is the end product, whether it’s a game or an engine. Anything developers can do to try out more ideas and make better software and games faster is a win for everyone.”
In replies, he argued that AI will help studios find a game’s fun earlier. Answering a user who said big-budget games have been struggling because they simply weren’t good enough, he wrote that “these projects went through 80%+ of their development timeline unplayable, and when the project was eventually supposed to come together, it was too late to make their unfun game fun.” He added, “AI will rapidly accelerate prototyping and ‘finding the fun’.” Asked how much faster prototyping is now, he answered: “About 5x faster to prototype right now with Unreal Engine and 10x with ThreeJS. Working to reverse the gap by year end.”
He also drew a line on how the tools should be used. “People who use AI to blindly build up bodies of code or content without providing creative or architectural insight are definitely doing it wrong and will end up with either an unshippable mess or shipping a bad product,” he wrote.
By Sunday morning the tone had sharpened. When an X user named Kenney posted, “Don’t let billionaires convince you slop is the future,” Sweeney fired back that he is “the same tech tree following optimist who moved from C to C++, from 2D to 3D, and from closed source to open source,” adding, “I run a company. I write code. I contribute to published papers. I’ve upped my expectations of AI.”
Sweeney also urged developers who use AI to say so publicly. “Developers who are getting value from AI should speak up. There’s safety in numbers,” he wrote.
