Arjan Brussee, a seasoned veteran in the gaming industry, is pushing for a Europe-built alternative to Unreal Engine called the Immense Engine. He wants to see a sovereign, EU-hosted, general-purpose 3D engine that could power games and a wide range of 3D applications across industries, all guided by European rules and standards.
The project leans on artificial intelligence to boost developer productivity. Brussee hopes it can match the capabilities of established engines while keeping European control front and center.
What is the Immense Engine?
The Immense Engine is pitched as a general-purpose platform designed to rival Unreal Engine, but with a distinctly European backbone. Brussee points out that there’s currently no major engine fully hosted in Europe, developed by Europeans, and compliant with European policy and guidelines.
He envisions not just game development but also a broader 3D toolset for simulations, architecture, automotive, and other industries where realistic rendering, physics, and AI-driven workflows are increasingly important.
Europe already has specialized engines—CryEngine in Germany comes to mind—but their adoption has been patchy, and their ecosystems are smaller. The Immense Engine would try to fill that gap by offering a scalable, modern platform that follows European data governance, export controls, and open standards.
In Brussee’s view, the project is as much about sovereignty as it is about performance. The goal is to build a homegrown alternative with an EU-friendly compliance posture.
There’s a strategic angle here too: Europe wants to reduce its dependence on non-European platforms for critical development infrastructure. The Immense Engine could attract European studios, researchers, and industrial partners who need deep customization and alignment with European rules.
That, in turn, could help strengthen domestic talent and supply chains in the digital-software space. It’s a tall order, but the ambition is clear.
European sovereignty and policy momentum
Europe’s tech policy landscape keeps shifting toward autonomy in critical stack components—development tools, data handling, cloud infrastructure. The Immense Engine fits right into this trend by offering a sovereign alternative shaped by European researchers and companies.
Governance would align to EU frameworks and standards. That’s a big deal for those wary of lock-in or external influence.
- Data sovereignty and privacy alignment with GDPR and industry-specific regulations
- Open standards and interoperability to avoid lock-in with non-European ecosystems
- Public and private funding pathways that support research, tooling, and long-term maintenance
- Strategic collaboration across European universities, studios, and enterprises to cultivate a robust ecosystem
AI-first approach and productivity claims
Brussee’s vision centers on an AI-driven framework of agents built into the engine. He claims this architecture could speed up workflows, handling tasks that would normally require much larger development teams.
He imagines the productivity of “ten or fifteen people” by automating repetitive or complex coding and content-generation chores. That’s a bold promise, but it’s hard not to be at least a little intrigued.
Experts caution, though, that turning AI-assisted workflows into reliable, reproducible, and safe production processes will take careful engineering and a lot of testing. Governance will matter too.
There’s an ongoing debate about what’s hype and what’s feasible here. Transparent milestones and verifiable performance metrics will be crucial as the project moves forward.
Feasibility, challenges, and the road ahead
The Immense Engine faces some serious technical, economic, and policy hurdles. Matching a mature platform like Unreal Engine will need big, sustained investment in tooling, plugin ecosystems, documentation, and a lively developer community.
The EU’s regulatory environment is a strength for sovereignty, but it can also bring compliance, certification, and procurement challenges. The project will need to tackle those head-on.
Tech comparison and potential impact
Technically, the Immense Engine has to deliver top-notch rendering, physics, and tooling, plus seamless support for AI-driven workflows. The real test will be how its ecosystem stacks up: performance, cross-platform support, and whether enough partners and content creators are willing to back a European alternative.
What this means for European developers
For European studios and researchers, a successful Immense Engine could give them more control over roadmaps, licensing, and data governance. That sounds appealing if you’re tired of jumping through hoops set by overseas platforms.
It might also spark more innovation in the region and help attract talent who want to work within a truly European tech stack. There’s a sense that this could reduce dependency on outside platforms, which—let’s be honest—has been a sticking point for a while now.
But will people jump on board right away? That’s going to depend on real, convincing demonstrations of reliability and extensibility, plus a clear plan for building a healthy developer community that doesn’t fizzle out after launch.
