It's not about luck, it's just the PC platform is for modding and that goes for a lot of games. An editor is only one thing for making mods, a lot of people use Adobe Photoshop for doing textures and 3D apps like 3D Studio Max for models, which require a lot of resources that a console could never do.
You are misunderstanding my use of the word lucky , I meant it as you PC owners are fortunate to get it and I'm aware the consoles are not powerful enough to run the CK , that's why I said it in my first sentence x_x
