Go into any remAining bookstore and you can find the choose your own adventure and other gamebook series where readers either take the role of the main character or guide him in decisions. Some use dice and D&D style battles. Others employ puzzles. Unfortunately, I have not seen a new original commercially sold gamebook in over 20 years. I liked the idea and wished they could flesh out the stories and improve, not cease creation. Visual novels are sold mostly in japan and offer a computerized version for the most part, but there are no print forms.
