Look at DAZ and EF and you see that V3 has only one neck (V2 has two), and Jessi has no buttocks. (Judy has them).
They both gave additional bodyparts a try and both changed direction later.

Actually, someone who should know said the reason Jessi has no buttocks is that e-Frontier is preparing for an advanced rigging system that will make the buttocks group unnecessary. That's why Jessi is rigged like Posette.

IMO, the Face Room is a failure because it doesn't use the DAZ figures. If it did, more people would learn to use it. As it is, we have people wandering in here at least once a week asking how to get Vicky into the face room.

I don't consider the cloth and hair room to be failures. They've just taken longer for the community to embrace. Partly because they're a little harder to use, but mostly because of Poser 5's flaws.

Poser is a tool to create pretty pictures, sometimes even art, and the easier this tool is to use, the more people will be able to use it.

If e-Frontier takes that tactic, the gaming industry (Second Life, The Movies, etc.) are gonna eat their lunch. They can't be as easy and as cheap as games.
