In our little universe the majority of the users basically just want to load premade content, pose premade content and hit render to make a pretty picture, these people are also where most of the money comes from that's kept the marketplaces in business.

Now DAZ realized this years ago which is why their figures always have a lot of content available when they release a new figure, when it was the millennium series nobody challenged them, figures were made but had very little content, so they were allowed to "rule" the content side of things.

Now that they don't create Poser figures most of the money spenders have followed them and now buy DS native content, so any marketplace that stayed "Poser only" was always going to suffer, as will any new Poser only marketplace.
