It was a render that got me into Poser.  A render of two Michaels. 

I asked the artist about it, and she told me about Poser.  Which I bought immediately.  (Little did I know that it was about a week before Poser 5 was released, and if I'd bought PP4 from Curious Labs instead of Amazon, I'd have gotten it for something like $50 cheaper.)

So I guess for me, it was content first.  I bought Poser because I wanted to use DAZ's Michael 2.

Back then, I really liked the idea of one figure you could morph to be anyone.  Guess I'd have loved Genesis if it were around back then.

But I've changed my mind now.  IMO, it just looks better if the figure isn't too far from the base. Which means multiple figures to cover the diversity of humanity (never mind critters and such).  Which means buying a lot of stuff, even with WW and texture converters.  ;-)
