It may have been noticed but mechanically I've been treating the CYOA a lot like a barebones rpg, I run and play pathfinder a lot so I did what I know. However I picked up a few CYOA books to amuse myself and found those with combat in, like the old Heroquest ones, function on a much simpler system, D6+stat, highist wins.
Should I still with the current system, treat it more like an rpg with the wildcards that introduces, and bad choises are more often negative modifiers to a situationthan a loss or make it more like a classic CYOA where many choises are good/bad/other preset by choises and not rolls. (for example spotting something hidden would be her spot stat vs i's stealth score, highist wins with no roll).
