Game Engine

The game engine is the technical foundation that coordinates rendering, audio, input, physics, animation, scripting, asset loading, and other runtime systems. It commonly includes editors and production tools so designers, artists, and programmers can assemble content without rebuilding core technology for each project. Studios may license a general engine, customize one, or maintain proprietary technology. An engine is not the finished game: rules, art, levels, story, interfaces, and much of the gameplay code sit on top of it. Engine choice affects workflow, supported platforms, performance, licensing, and hiring.
