Castle Game Engine vs Godot Engine

Castle Game Engine is a free, open-source engine for building 2D and 3D games with a visual editor and an Object Pascal API. The editor supports designing game worlds and interfaces, then building projects for multiple platforms. Listed targets include Windows, Linux, macOS, Android, and iOS, with mobile export, console export, and multiplayer tools. Graphics capabilities include shader effects, physically based rendering, shadows, mirrors, bump mapping, and post-processing. Supported formats include glTF, X3D, sprite sheets, and Spine 2D animations. The project lists Visual Studio Code, Lazarus, Delphi, Blender, and Sketchfab among supported tools and services. A command-line build tool, Docker image, and CI setup documentation support automation. The engine can be used for proprietary applications. Provided Linux binaries require GLIBC 2.34 or newer; older systems can compile from source. Supported operating systems must still receive vendor security support, with Windows 10 temporarily supported as of 2026.

Godot Engine is a free, open-source engine for developing 2D and 3D games, cross-platform projects, and XR ideas. Its Node and Scene system organizes game logic through reusable components and hierarchy. The dedicated 2D engine uses pixel coordinates and 2D nodes, while 3D nodes support building, animating, and rendering worlds and characters. Developers can use GDScript, C#/.NET, or C++ through GDExtension, along with community language bindings. Godot includes OpenXR and WebXR support, with other XR SDKs available through plugins. Games can be published on desktop, mobile, and web; console deployment is supported through third-party publishers. The engine uses the MIT license, which permits commercial use and redistribution subject to including its copyright notice and license statement. That license does not apply to content made with Godot, and creators retain copyright ownership of their games. C# is available for desktop and mobile; the listed web option is Godot 3. The latest stable download listed is Godot 4.7.2.
