Introduction
Game engines are software frameworks designed to help developers build video games and interactive experiences efficiently. They provide essential tools such as rendering engines, physics systems, scripting environments, asset management, and deployment pipelines—all in one unified platform.
Today, game engines are used far beyond gaming. They power simulations, virtual production, architecture visualization, AR/VR applications, and even training platforms. With advancements in real-time rendering, AI-assisted development, and cross-platform support, choosing the right game engine is a critical decision for developers and organizations alike.
