When comparing CopperCube vs Crystal Space 3D, the Slant community recommends Crystal Space 3D for most people. In the question“What are the best 3D game engines?” Crystal Space 3D is ranked 40th while CopperCube is ranked 43rd. The most important reason people chose Crystal Space 3D is:
Scripting language biddings are available via swig, supposedly any swig target could be used If you are okay with building, and probably maintaining, the project for your own needs then you may be able to build bindings for your favorite scripting platform. As noted in a slant "con", there are no binary releases, including no prebuilt bindings.

Expect to compile this from source if your want to play with it.
Ubuntu has a package for it, but that package appears to be missing it's scripting language bindings. I expect the build is also quite old and i fear may be dropped in coming Ubuntu releases.
