Xbox Manager Says Anyone Can Build a Game With AI, Then Deletes His Account

Xbox senior business strategy manager Brandon Stirrup spent October 18 telling X that anyone can build a game with AI. His account is gone.

He deleted it inside a day. A source at Xbox told PC Gamer that Stirrup deactivated the account because of the volume of replies, which arrived after a thread that worked through studios, developers and players in roughly that order and finished with him saying he was happy to be fired over it.

The thread opened with a build log. Stirrup said he had vibe coded a bad but improvable game across two days with around three hours of real work in it, and offered that as proof that anyone can build a game. From there he argued that studios not folding AI into their strategy are planning for a fake future, that a simple prompt can produce a custom game, and that he was willing to take the hit if it got hundreds of people at Xbox to stop pretending they do not use AI. He framed the stakes himself, writing that if he were fired the next day it would be for telling a truth nobody wanted told, and that some people would persecute him for stating plainly that Xbox uses AI the way every company does in 2026. The line that travelled furthest was his claim that a designer who refuses to believe AI has a place in their future should not be in the business of being a business.

“Gaming is the only industry where leaders are afraid to talk about AI.”

Xbox had already said a version of this, more carefully. On October 13, CEO Asha Sharma told staff she had commissioned XBOX LABS, a small group of game makers, engineers and scientists whose job is turning emerging ideas into things players and developers can use. The memo opened on what Sharma said she had been watching: games decompiled and rebuilt for hardware they were never written for, Windows builds translated onto Apple Silicon or pushed into a browser through WebAssembly and WebGPU, the latter now close to 90% global browser support, and large games remixed into each other’s source code. Her memo argued that coding became the first major workload for agents because agents can write, run and test software, and that games share those properties, with players spending more than 72 billion hours a year in Xbox games against an estimated global total for writing code roughly five times smaller. The memo also listed what is not changing: the 4Cs, hardware, and stewardship of IP.

Stirrup posted into the back half of an Xbox major reset that began in June, after Sharma replaced Phil Spencer and Sarah Bond and moved to steady a brand that had lost subscribers to a 50% Game Pass hike, dropping the This is an Xbox campaign and confirming new hardware under the name Project Helix. That reset has since run through a third console price rise in 14 months, pushing the Series X to $799.99, a pulled funding deal with IO Interactive, and closure consultations at Arkane and Ninja Theory.

In September, content chief Matt Booty told staff the company was cutting 268 employees across Halo Studios, other first-party teams and the XGS management layer, while folding World’s Edge and Rare under Activision and Obsidian under Bethesda. In the same month, Stirrup advised laid-off employees to use Copilot to catalog their skills and accomplishments at the company.

Epic has been louder for longer. In October it shipped a rebuilt Epic Games Store client that its own blog post called vibe coded, and store GM Martin Keely confirmed AI wrote the new code rather than reviewing the old. Sweeney said Epic has a huge pivot underway, “moving developers around to retool for maximum AI acceleration,” after Bloomberg reported that the team on an unannounced Star Wars and Marvel shooter had been told to work AI first. Epic says the rebuilt client halves startup time and reaches the store 46% faster than Steam from cold, and it ships with a Linux build for the first time.

I use these tools every working day, and the jump from a three-hour prototype to anyone can build a game is the part of the thread that does not follow. Those are two different claims, and only the smaller one came with evidence attached.

What I want out of a game is a world dense enough to get lost in and choices that cost something, and no prompt produces that yet. A bad but improvable game demos the tooling. The thing players pay for sits somewhere else entirely.

Xbox’s own cheque book makes the point better than the replies did. The company picked up Kojima’s Physint after Sony declined to fund it, with Jason Schreier reporting that the initial budget was significant and that Xbox is paying somewhat less than Sony would have. That is a large auteur-led project bought at full human cost, in the same year a strategy manager told X that a prompt can hand a player whatever they want.

Platform pressure explains some of the volume. Tom Warren reported that GTA 6 pre-orders on PS5 are far ahead of Xbox Series X/S and that the gap has unsettled people inside the company; Xbox responded through CFO Matthew Ball, who said the company is very happy with the numbers, that the game is breaking records for Xbox, and that its share of pre-orders matches its share of the console market. IGN put the pre-order split at six to one in Sony’s favour back in June. GTA 6 arrives on November 19.

The features players actually noticed this autumn came from a quieter part of the building. Mythic Achievements, Xbox’s answer to the PlayStation Platinum trophy, surfaced in an Xbox PC app update: clear every achievement in a base game and it unlocks, with no Gamerscore attached and retroactive credit for games already finished. Insider Klobrille pulled the icon, animation and unlock sound out of the same build, and Sharma had hinted at a Platinum equivalent back in August.

I would take Stirrup’s argument further if it had come from someone outside the company doing the cutting. The tools are real and Xbox was going to say so eventually. Saying it as a strategy manager, in the same quarter as the layoffs, turned a technology argument into a loyalty test, which is roughly the opposite of what the thread set out to do.

Read also, Xbox had bigger plans for Halo than the single remake it shipped this summer. Halo 2 and Halo 3 remakes under the codename Project Manihi were in concept at Halo Studios before the layoffs, with dual wielding and a fuller multiplayer for the second game and Forge, Theater and Firefight for the third.
