When you think back to the earliest incarnation of this story you can remember that reasonably resembles what we have now--be that an outline, a rough draft, loose collection of ideas, etc--has it changed much in terms of the overall structure, theme, or tone?
If so how much of this do you attribute to the medium (Visual Novels) you're working in?
How has your approach to writing or overall workflow developed as you've been working on Nerus?
Of course they're all your precious creations and serve a purpose, but was there anyone in the supporting cast who didn't initially have a sprite that slowly became one of your favorites once there was a visual component to them?
