They put "vibe" in quotes because "it takes a lot more skill than just prompting."

An ex-Blizzard employee claims to have "vibe" coded an engine for their new game. The game is Em-8er and is "entirely 'vibe' coded" in the Kun-Zhi Engine.
"I spent 6 months using AI to replace Unreal Engine from under our game Em-8ER. Now we're developing 93x faster than we ever did before with Unreal. Because our engine is developed to be 100% AI-first instead of tacked on."
"The engine is called Kun-Zhi, the Tibetan word for 'Ground of all' that the world springs from. This engine will be released to the public, starting with backers first... Corporate sponsorships are available... Current partners include Razer and AMD."
"This," the dev says, "is a ground up engine written mostly in C [and also with "some Elixir"] on top of Vulkan."
The developer behind it is Mark Kern, a developer who worked for Blizzard on World of Warcraft (vanilla) and then helped found now-dead studio Red 5 Studios, makers of the equally dead game Firefall.

The eagle-eyed among you will notice that Kern puts "vibe" in scare quotes. This, he says, is "because it takes a lot more skill than just prompting. To be production ready you have to have knowledge of how games are put together and how to guide the AI."
"The data structures and architecture become more important. The coding was always the drudge part."
