One of the main differences is that it is completely in the cloud (which required the most effort on the development side). The "we have some artists" approach has some serious limitations if you start growing the number of artists and number of 3D scenes that they are working on (and turns into a complete mess if you take versioning, continuous asset updates, and remote work into account). The other difference would be the content: that we are continuously uploading products and materials (which our users can access from the public library), and which you would have to build from scratch or source them from somewhere with the above approach.
