Do you really want players who solely focus on eye candy though? Don't get me wrong it's nice, but the thing that brought me in was the writing. I'm sure you didn't spend all that time planning before you even rendered anything focusing on what it would look like?
Other than character design? No. Never gave it a thought! XD
There was a bit more to it than this, but basically it went:
Has idea for a story
Plotted it
Decided what fancy bits I wanted (so the PDA for example)
Broke it down into chapters
Designed all the characters
Did the tutorial as a code learning exercise
Then got to grips with Daz
Wrote the first chapter
Then worked out how to code it!
Then worked out how to code the fancy bits!
Then rendered
*is -such- an expert!*
