From Epic and Guerilla to a New AI-First Engine
Arjan Brussee, known for co-founding Guerilla Games and serving as a technical director at Epic Games, is now focused on a very different mission: creating The Immense Engine. Framed as a new kind of Unreal Engine competitor, his work-in-progress platform positions itself among emerging game engine alternatives designed from day one around AI game development. Rather than bolting AI tools onto an existing stack, Brussee wants generative systems as a core architectural principle. The Immense Engine is being pitched explicitly as a fully locally hosted, compliance-conscious stack, targeting not only games but broader 3D applications such as simulation and training. For developers wary of depending on long-established engines, this project symbolizes a shift toward AI-native workflows and more diversified infrastructure, potentially changing the calculus for teams deciding where to build their next projects.
AI Game Development at the Core, Not as an Add-On
What distinguishes Immense Engine in a crowded field of game engine alternatives is its promise of “full” generative AI integration. Brussee argues that the rise of AI demands a new approach to crucial software, emphasizing automation over menu-driven manual work. His vision is to orchestrate a framework of cooperating AI agents that can shoulder tasks currently handled by teams of designers, artists, and technical staff. According to his comments, a well-structured AI system could do the work of ten or fifteen people, dramatically reshaping production pipelines. This aligns Immense Engine squarely with the AI game development movement, where engines become orchestration layers for content-generating models. While Unreal and other incumbents are also experimenting with generative tools, Immense seeks to differentiate by embedding these capabilities deeply into its foundation rather than treating them as optional plugins or sidecar services.
Strategic Independence and a Locally Hosted Technology Stack
Beyond pure technology, Immense Engine carries a strategic message about digital sovereignty and infrastructure independence. Brussee describes his platform as fully locally hosted, built by local teams, and aligned with local regulatory frameworks. This positioning resonates with broader debates about reliance on major US-based platforms for critical software, especially where engines underpin not only games but military and industrial simulations. For institutions and studios concerned about where their data resides, how their tools are governed, and which legal regimes apply, such an engine offers a symbolic and practical alternative. It underscores a desire to cultivate local technology ecosystems rather than leaning exclusively on globally dominant engines. This narrative could prove compelling for public-sector clients and large enterprises, where compliance, control, and long-term autonomy often matter as much as rendering features or visual fidelity.
What Immense Engine Could Mean for Indie and AAA Studios
For developers, Immense Engine’s ambitions open new strategic options in a landscape long defined by a few major tools. Indie creators frequently seek game engine alternatives to avoid lock-in, complex licensing, or shifting corporate priorities. An AI-native engine that automates asset creation, level design, or testing could lower barriers for small teams, allowing them to prototype faster and tackle more ambitious projects. On the AAA side, large studios may view Immense as a way to rebalance dependencies and experiment with different technology stacks tailored to their pipelines. However, the promise of AI game development also raises questions about workforce impact, long-term maintainability, and whether generative systems can reliably deliver production-quality results. Until Immense Engine is publicly available and battle-tested, it remains a high-potential Unreal Engine competitor whose real influence will depend on tooling maturity, ecosystem support, and how convincingly it can integrate AI into everyday development.
