I imagine you may have just a few questions after reading that title. The first is probably something along the lines of "Didn't you just play your first visual novel like a month ago? Aren't you skipping some steps?"
Adaptations are weird. Doing it well, whether that's adapting a book into a movie, a game into a movie, anime, or even visual mediums into books, it seems to be less about skill and knowledge and more about artistic ability and the creator's discretion.
A gamebook is what it sounds like. It's a book that tells a fictional story that you get to participate in one way or another rather than just reading. It's why you may ask the question of what verb you're supposed to use when talking about it.
However, for something like a story, you need to be a little more concise. It's important to do more with less if you want to keep people interested in your plot. That isn't to say you shouldn't take the time to tell a joke or to add in a scene that's not incredibly relevant.
