What are Game Engines?

A game engine is a software framework designed to facilitate the development of video games by providing essential tools and functionalities. It typically includes a rendering engine for graphics, a physics engine for realistic object interactions, and scripting capabilities for game logic. Many game engines also offer asset management, animation tools, networking support, and AI systems to streamline development. Popular engines like Unity and Unreal Engine enable developers to create games across multiple platforms with minimal additional coding. By handling complex technical aspects, game engines allow creators to focus on designing immersive gameplay experiences.
