The Rise of a European Gaming Titan: Why Arjan Brussee’s Immense Engine Could Redefine the Industry

There’s something undeniably bold about Arjan Brussee’s latest venture. The gaming industry veteran, known for co-founding Guerrilla Games and his tenure at Epic, is now setting his sights on something far bigger than a new game or studio—he’s building an entire game engine. But this isn’t just any engine; it’s a European-born, European-hosted, and European-compliant powerhouse called the Immense Engine. Personally, I think this move is more than just a business decision; it’s a statement. It’s a declaration of Europe’s ambition to carve out its own space in a market dominated by giants like Unreal and Unity.

What makes this particularly fascinating is the timing. As the gaming industry expands beyond entertainment into sectors like education, architecture, and even healthcare, the demand for versatile 3D engines is skyrocketing. Brussee’s emphasis on AI integration isn’t just a buzzword—it’s a strategic play. He’s not just building an engine; he’s envisioning a tool that could revolutionize how we create and interact with digital worlds. If you take a step back and think about it, this isn’t just about gaming; it’s about shaping the future of digital creation itself.

One thing that immediately stands out is Brussee’s critique of existing engines. He argues that they’re built for a mouse-and-menu generation, lacking the flexibility needed for modern development. This raises a deeper question: Are we still designing tools for the past? Brussee’s approach, with its focus on AI agents and modularity, feels like a leap into the future. What this really suggests is that the industry might be overdue for a paradigm shift—one that prioritizes efficiency and adaptability over tradition.

From my perspective, Brussee’s European focus is both a strength and a challenge. On one hand, it’s a brilliant move to tap into Europe’s rich talent pool and regulatory framework. On the other, it risks limiting global adoption if developers outside Europe perceive it as too region-specific. What many people don’t realize is that Europe has been a silent powerhouse in gaming innovation, from Crytek’s CryEngine to Guerrilla’s Decima. Brussee’s engine could be the catalyst that finally puts Europe on the map as a major player in game engine technology.

A detail that I find especially interesting is Brussee’s claim that AI can replace the work of 10–15 people. While this might sound like hyperbole, it’s not entirely far-fetched. AI-driven tools are already transforming industries, from film to manufacturing. In gaming, where development cycles are notoriously long and costly, this could be a game-changer. However, it also raises ethical questions: What happens to the workforce if AI becomes the primary driver of creation? Brussee’s engine could become a case study in the balance between innovation and human labor.

If you ask me, the Immense Engine isn’t just a technical project—it’s a cultural one. It’s about Europe asserting its identity in a global industry. It’s about challenging the status quo and reimagining what a game engine can be. Whether Brussee succeeds or not, his ambition alone is enough to spark a conversation about the future of gaming technology. Personally, I’m rooting for him. Because if there’s one thing the industry needs, it’s more visionaries willing to take bold risks.

In the end, the Immense Engine might just be the first step in a much larger movement. It’s a reminder that innovation doesn’t always come from Silicon Valley or Seattle. Sometimes, it comes from a veteran developer in Europe, armed with a vision and the courage to build something entirely new. And that, in my opinion, is what makes this story so compelling.
