You may wonder, "i remember that title, but something changed" ^^
Yes i posted some days ago about the unreal engine being free for non-commercial use, and now Crytek seems to think, "we must do this, too".
So now you can register for an educational license of the CryEngine 3 and the very new Sandbox-Editor version on mycryengine.com/
This makes the third part in the rush of making great game engine free for pulic: Unity, Unreal and now CryEngine.
