One of the things I first picked up Daz for was to make a VN, as I can't draw traditional art. I already had the bones of a script written, and was working on character designs when my current webcomic project was born.
Still have no desire to code, though. Gonna have to let someone else handle those particular reins.
But yeah, doing VN assets, sprites, etc. is something I'd like to do in the future. Don't have much desire to do adult/porn stuff though, which it seems is where 90% of the demand is.
