I have read/played quite a few visual novels and am interested in the process of creating one.
Where can I find (preferrably free) online resources, such as How-To-Write or styleguide articles and blogs, about writing a visual novel?
The main reason for asking specifically about a visual novel is that I am having problems with the idea of creating a branched storyline and would like to see what common ways are for creating such a story.
Furthermore the way of presenting the story has always reminded me of theater and I would like to see whether visual novel authors use different formatting or descriptions when writing than text-only novel authors.
The fact that players can choose a path and that I have seen different ways of presenting these options is also fascinating, because some visual novels were giving the complete text a character would say while others would summarize the main content and I am not sure whether there are guidelines for what way should be preferred.
