A Game Engine is a software framework designed for the creation and development of video games. It provides developers with the necessary tools and features to build games efficiently, including graphics rendering, physics simulation, and sound management. Popular game engines like Unity and Unreal Engine enable both indie developers and large studios to create immersive gaming experiences. Game engines streamline the game development process by offering reusable components and a user-friendly interface. They often support multiple platforms, allowing developers to deploy their games on various devices, such as PCs, consoles, and mobile phones, thus reaching a wider audience.
