I find the arguments of procedural vs artistic content somewhat humorous given that artistic content is just an attempt to create something that is a fascimile of actual natural and human generated artifacts. The natural world is by definition procedural (unless you believe in a Creator). The human artifacts have some artistry - but only in the broad strokes. Most buildings, and most details of architected buildings, follow a procedural semantic. The natural decay of human artifacts follow a procedural semantic.

I assume that in the near future of VR that few will play "AAA games" (and hence few will exist) because they won't be able to complete with free procedurally generated environments.
