Hmm. Well that's an interesting perspective. Although, I suspect your dislike for NVL mode is matched only by my dislike for ADV mode. My belief is that ADV mode adds to the "puppet show" feeling of a VN. My perception of NVL mode is: it's like reading text on top of an image, which is intended to convey the general feeling of the scene. But yes, I do worry that since we have so many expressions, interrupting the NVL window every 30-or-so seconds will become irksome to the reader.
So, while I dislike ADV mode, I'm certainly not adverse to the idea of exploring alternatives.
I suppose the simplest compromise would simply be using NVL mode whenever there are no characters on screen, and then switch to ADV when there are characters on screen.
While I haven't played Torrey and the Vampire (and am not in a position to even check it out for the better part of a day), I am curious about their solution. I assume it was an NVL window that only took up half the screen?
Come to think of it, I believe Doomfest released a little game a while ago that messed around with the NVL window. Memo, if I recall correctly. Although, in this case, the NVL window was off to one side.
You know, given the nature of wide-screen displays, that might be a viable option as well—placing the NVL window along the left side of the screen, leaving the right side clear for sprites. In a way, it'd almost be like looking at a two-page layout in a book, with text on one side and images on the right.
Although, even that has it's issues. Cheif among them being the fact that any time any graphical changes are invoked, the NVL window WILL disappear. I believe Archer asked PyTom once about making it not disappear, to which PyTom effectively responded, "Why would you want to do that?".
