How long does it take to write a choose your own adventure story?

Writing a choose your own adventure story takes anywhere from an afternoon to several months, depending on how many branches and endings you plan. A short piece with one central choice and three endings can be drafted in a few hours. A full gamebook with dozens of interconnected sections is closer to writing a novel, because every branch is extra words plus the work of keeping them consistent. The structure usually takes longer than the prose: mapping which choice leads where, catching dead ends, and testing every path. A good first project is small, maybe 15 to 25 sections, which teaches the branching discipline without burning you out. Building the map visually first, in a tool like the Visual Builder, saves a lot of rewriting later.
