Unreal Engine review

Unreal Engine offers the most advanced 3D toolset here at no upfront cost. Epic's license page makes it free for game developers, with a 5% royalty on all lifetime gross revenue above $1M that comes from a product, and sales through the Epic Games Store are royalty-free. Non-game commercial users above $1M pay $1,850 per seat per year instead. The engine includes Lumen global illumination, Nanite geometry, World Partition for large worlds, a full animation stack and MetaHuman for realistic characters, plus access to the source code and all platforms. That power comes with a learning curve that is much steeper than Godot or GameMaker, and teams must submit a release form and report royalties each quarter once a game ships. For 2D or small mobile projects it is more engine than most hobbyists need.

Who it is for
