une recherche de 5 seconde sur google et j'ai trouver ça:
Hmmm i think you dont understand what crystalspace is?
Its nothing like the blender out of the box gamekit.
Crystalspace is a SDK, a collection of libraries and helperclasses to implement in a pice of code. You can use crystalspace to code your own 3D Widget. Its nothing you install and run. You code, implement and compile.
Maintenant à toi de traduire;)
