Game Engine

A game engine is a software framework or platform that provides the fundamental tools and components necessary to create and run video games.

It serves as the core infrastructure for game development, offering features like graphics rendering, physics simulation, audio processing, and input handling.

Game developers use these engines to streamline the game creation process, allowing them to focus on designing gameplay and content rather than building complex technical systems from scratch.

Popular game engines include Unity, Unreal Engine, and CryEngine, which offer a wide range of tools and support for various platforms and game genres.

This was shaking the business model of many game developers.
