Game engines are integrated software development platforms designed to create video games. They provide core systems including rendering, physics simulation, audio processing, and asset management, enabling developers to build games for PC, console, mobile, AR, and VR platforms.

Game development studios use game engines to accelerate the development process by leveraging pre-built components rather than coding every system from scratch. The engine handles core technical challenges like graphics rendering, physics calculations, and memory management, allowing development teams to focus on game design, content creation, and unique gameplay features. Studios select the [best game engines](https://learn.g2.com/best-game-engine) based on factors including target platforms, technical requirements (2D vs. 3D, multiplayer support, etc.), and their team's expertise.

To qualify for inclusion in the Game Engine category, a product must:

- Be designed specifically for video game creation
- Provide native real-time graphics rendering, physics simulation, audio processing, asset management, and scene and level editing
- Support at least one major gaming platform (PC, console, or mobile)
- Offer documented APIs or SDKs for game development
