More. Better.

Anything that helps people create art is a good thing. Selling it comes with two sides. ok, more than two, but I'll just do two.
The people who have been with Bryce for years are used to a community where knowledge is shared and a large part of the art is making things yourself, or giving them away.
DAZ is drawing people from poser to Bryce, this is a good thing. An injection of new talent and ideas is needed for Bryce to renew its energy. These people have probably been purchasing content for poser for some time so purchasing content for Bryce won't be new to them.

I've completly lost my train of thought cause everyone is talking in chat right now.
Go for it! Make it! Sell it! Grow the pool of artistry and talent!
