Former Epic director is building a European rival to the Unreal and Unity game engines — 'The Immense Engine' developer sees opportunity for AI agents to 'do the work of ten or fifteen people'

Arjan Brussee says he is building The Immense Engine, a Europe-hosted game engine made by Europeans.

The project aims to offer an alternative to Unreal and Unity that follows European regulations.

AI agents may help a small team do the work of many developers.

The engine could also serve defense, logistics, and government simulation needs while reducing reliance on U.S. and Chinese platforms.
