The Great Tech Decoupling: Is Europe Finally Breaking Free from Silicon Valley?
For decades, the global tech landscape has operated under a quiet assumption: the most powerful tools are built in California, and the rest of the world simply licenses them. From the operating systems running our government offices to the engines powering our most immersive virtual worlds, the “US-centric” model has been the default. But a shift is happening. There is a growing “vibe” across the continent—a sense of digital fatigue—that is pushing Europe toward a strategy of digital sovereignty.
This isn’t just about politics; it’s about infrastructure. We are seeing a trend of “quiet quitting” regarding American tech giants. A prime example is the French government’s recent strategic transition from Microsoft Windows to Linux, signaling a desire to reduce dependency on proprietary US software in critical state infrastructure.
Beyond Unreal: The Ambition of the Immense Engine
Nowhere is this quest for independence more ambitious than in the world of high-end 3D rendering. For years, Unreal Engine has been the undisputed “load-bearing pillar” of the industry. It doesn’t just power blockbusters like Fortnite or Mass Effect; it has migrated into Hollywood (powering The Mandalorian) and the wild world of high-production YouTube content.
Enter Arjan Brussee. As a co-founder of Guerrilla Games (the studio behind Horizon: Zero Dawn) and a veteran of Epic Games, Brussee possesses the rare combination of entrepreneurial success and deep-level technical knowledge of how the industry’s biggest engines actually work.
His new project, the Immense Engine, isn’t just another piece of software; it’s a bid for a “fully European” alternative. The goal is a general-purpose engine that is hosted in Europe, built by Europeans, and designed from the ground up to comply with European rules and guidelines—most notably the strict mandates of GDPR.
The “CryEngine” Cautionary Tale
Building a competitor to Unreal is a Herculean task. Europe has tried this before. Germany’s CryEngine, famous for the Far Cry series, proved that you can build a technically stunning engine but still struggle with widespread adoption. The “network effect” of Unreal—where every artist and developer already knows how to use the tool—creates a massive barrier to entry for any newcomer.
For the Immense Engine to succeed, it cannot simply be “as good” as Unreal; it must offer a fundamental advantage. For Brussee, that advantage appears to be a combination of regional sovereignty and a radical new approach to development.
The AI Wildcard: Coding at 15x Speed
The most provocative aspect of the Immense Engine isn’t its origin, but its construction. Brussee has hinted that the rise of AI changes the math of software development. He suggests that by utilizing a framework of AI agents, a small, elite team can effectively do the work of ten or fifteen people.
This “AI-pilled” approach to coding represents a broader trend in the industry: the shift from manual line-by-line programming to AI-orchestrated development. If a small European team can maintain a world-class engine with a fraction of the headcount required by a giant like Epic Games, the economic barriers to entry vanish.
Why Digital Sovereignty Matters for the Future of 3D
Why does it matter if a game engine is “European”? To the average gamer, it doesn’t. But to the industries building the “Industrial Metaverse,” It’s critical. When 3D worlds are used for urban planning, defense simulations, or medical training, the question of where the data lives and who owns the pipeline becomes a matter of national security.
By creating a general-purpose engine that adheres to EU standards, Brussee is positioning the Immense Engine not just as a tool for games, but as a piece of critical infrastructure for any European entity that needs to create usable 3D worlds without exporting their intellectual property to US-based cloud servers.

Frequently Asked Questions
What is the Immense Engine?
It is a proposed general-purpose 3D engine being developed by Arjan Brussee, aimed at providing a European-hosted, GDPR-compliant alternative to the US-based Unreal Engine.
How does it differ from CryEngine?
While CryEngine focused heavily on the first-person shooter genre and struggled with broad adoption, the Immense Engine aims for “generalizability,” targeting industries beyond gaming, such as film and simulation, while leveraging AI to accelerate development.
Why is the French government switching to Linux?
The move is part of a broader trend toward digital sovereignty, reducing reliance on proprietary American software (like Microsoft Windows) to ensure better control over security and data.
Can AI really replace a large team of developers?
While AI cannot yet replace high-level architectural decision-making, “AI agents” can automate repetitive coding tasks, debugging, and boilerplate generation, significantly increasing the output per developer.
