Castle Game Engine is a cross-platform 3D and 2D game engine.

You can use any 3D or 2D software to create models in various formats: glTF, X3D, VRML, Spine JSON, Collada.... In particular creating game models in Blender is fully supported, through the glTF format.

The engine can be used to compile desktop (Linux, Windows, macOS), mobile (Android, iOS) and consoles (Nintendo Switch) games.

You can design and build applications in a visual editor. The editor utilizes a command-line build tool under the hood. The build tool calls FPC and some other tools to compile and run the project.

Many graphic effects are available: physically-based rendering, shadows, mirrors, bump mapping, shader effects, gamma correction. Rendering is done through OpenGL or OpenGLES.

Numerous services, like in-app purchases and game services, are available on mobile devices. See Android servcies, iOS services.

The user interface is cross-platform and supports anchors and automatic scaling.

The engine is open-source. The engine may be used under GNU LGPL with "static linking exception", just like FPC RTL and Lazarus LCL. So you can make both open- and closed-source games.
