FF books also have more complicated graphs connecting their passages than CYOA. CYOA books are generally tree-like with maybe a few extra connections that make them technically DAGs, e.g. https://outspaced.fightingfantasy.net/SVG_Flowcharts/CYOA001.svgz https://outspaced.fightingfantasy.net/SVG_Flowcharts/CYOA001... Fighting Fantasy book graphs are larger and can have cycles: https://outspaced.fightingfantasy.net/SVG_Flowcharts/ff01.svgz https://outspaced.fightingfantasy.net/SVG_Flowcharts/ff01.sv... This, combined with inventory tracking, contributes a lot to making them more interesting. You can do things like find a locked door, find the key for it somewhere else, and come back and unlock it, which is not possible in a CYOA.
