What a great post. I don't like to write long posts so I will answer briefly.
I hate DAZ. I used to work in it and literally cursed every minute in it. It's too slow, slow viewport, no hotkeys, no normal render engine, no full ability to customize materials, bad lighting, terrible interface, etc.
When you talk about posing, you're probably right. But you still won't be able to do a complex pose. The animation tools are probably fine for some simple animations, but you won't be able to do a complex animation like a bird flying or dancing.
My main point was that DPC can't do what it wants to do because of the technical limitation of DAZ. That's true. He can't do smoke simulation and he has to draw smoke manually in After Effects or other video editor. He can't make a simulation of bubbles in the bathtub and he has to draw them manually in photoshop. All of this takes time. He talks about artistic vision, but it was initially limited when he decided to work at DAZ.
When we talk about DPC we don't mean graphics. That's not his strongest part. The graphics in his game are average, but in terms of animations, minigame quality, branching he's probably the best. DPC isn't perfect and if he wanted to be the best in all areas one episode would have been in development for 2 or 3 years.
