I'd actually be interested in trying it out one day, but unfortunately I'm not artistically inclined.lol, everything always seems easy and quick when you don't do it.
I'm curious to know what you think could be automated?
If the Word document is correctly constructed (with, for example, a pseudo tagging system: [Sophia]; [image1]; [music1]; [fade]; [if --var]; [jump --scene1] etc.) and the files used intelligently named, a simple script can take care of translating it into renpy code.
All that's left to do then is to change the default values of certain parameters and do the rare cases that are a little complex by hand.
But making such a script wouldn't make sense in itself, because directly programming a few Word pages once they've been written is probably just as quick as tagging them...
