- Quick Answer: Industry veteran Arjan Brussee is reportedly developing “The Immense Engine,” a new AI-focused game engine positioned as a fully European alternative to platforms like Unreal Engine and Unity. The project is said to prioritize AI-driven workflows, automation, and European-hosted infrastructure, with Brussee arguing that future game development may rely heavily on intelligent systems capable of dramatically reducing the need for large development teams.
A longtime game industry veteran with deep ties to both Epic Games and Guerrilla Games is reportedly developing a brand-new game engine designed to challenge major platforms like Unreal Engine and Unity, while also positioning itself as a fully European alternative in an industry largely dominated by American and Chinese technology companies.
The project (known as The Immense Engine) is being led by Arjan Brussee, a developer whose career stretches back decades and includes work on Epic’s classic Jazz Jackrabbit titles during the 1990s, co-founding Guerrilla Games in the early 2000s, and later returning to Epic Games in a senior leadership role connected to Unreal Engine development and product management.
Why Does Brussee Believe The Industry Needs A European Game Engine?
According to reports and translated comments from Dutch podcast De Technoloog, Brussee believes there is currently a major gap in the market for a game engine that is entirely European-hosted, built within Europe, and aligned with European regulations and infrastructure standards.
While engines like Unreal and Unity continue to dominate game development globally, Brussee reportedly sees increasing demand for software platforms that comply more closely with EU guidelines, particularly as concerns surrounding digital sovereignty, cloud infrastructure, and data handling continue growing across Europe.
He also suggested that a European-first engine could have uses far beyond traditional gaming, especially in sectors such as logistics, military simulation, engineering, urban planning, and other industries that rely heavily on large-scale interactive 3D environments.
One notable aspect of The Immense Engine is its apparent focus on AI as a central development tool.
Brussee reportedly argued that many of today’s biggest engines were built around older workflows that depend heavily on traditional menus, manual editing systems, and complex user interfaces originally designed decades ago.
In his view, the rapid rise of AI is changing the way software should be developed entirely, and future engines may need to be structured around automation and intelligent systems from the beginning rather than simply layering AI tools on top of older foundations.
Could AI Replace Larger Development Teams?
Reports suggest Brussee sees major potential in AI agents that can automate significant portions of development work.
During the interview, he reportedly claimed that developers who understand how to properly organize AI-driven workflows could potentially achieve the output of teams far larger than themselves, even suggesting that a well-structured framework of AI agents could perform the work traditionally handled by ten or fifteen people.
While Brussee has not fully explained how these systems will function within The Immense Engine itself, the comments strongly imply that AI-assisted creation, automation, and workflow optimization are central pillars of the project’s long-term vision.
At the moment, The Immense Engine still appears to be in relatively early development, and there is currently no release window or demonstration showing how the platform compares technically to established engines like Unreal or Unity.
Even so, the project has already started generating significant discussion online due to its combination of AI-focused design, European positioning, and the reputation of the veteran developer behind it.
Whether it ultimately becomes a serious competitor in the engine market remains uncertain, but the project is already being viewed as one of the more ambitious attempts to rethink how modern game engines could function in the AI era.
