I'm seeing some RPGs that uses Squiffy, or maybe some other function, but I can tell from just the structure. If anyone has insight, let me know.

Well, they are using squiffy for the overall pathing (even if there is random deterministic stuff going on). But a lot of that requires Java Scripting to get such things as randomness and combat systems. Squiffy makes a good framework but dosn't quite have the horsepower to get it out of the trickledown gamebook pathing - it needs the boost of Java.
