Unity

Unity is a cross-platform game engine and development environment used by indie developers, studios, and enterprises to create 2D and 3D games, interactive experiences, and real-time simulations. It features a visual scene editor, a C# scripting system, built-in physics and animation tools, and support for deploying to dozens of platforms including Windows, macOS, iOS, Android, PlayStation, Xbox, and WebGL. Unity is one of the most widely used game engines globally, with a large ecosystem of assets, plugins, and community support. The editor itself runs on macOS, Windows, and Linux, and requires a licensing arrangement (free for individuals below a revenue threshold, or paid commercial licenses).
