head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
A hidden-object mystery about searching scenes and solving puzzles to crack a case.

Optimization · Pure Optimization
A noir Fables investigation where QTE action wraps a scripted mystery with limited genuine deduction.
9 Clues: The Secret of Serpent Creek leans Optimization (Pure Optimization); The Wolf Among Us leans Optimization (Pure Optimization).
The Wolf Among Us leans a little harder on execution, though the gap is small.
9 Clues: The Secret of Serpent Creek
Clicking hidden objects needs only patience
The Wolf Among Us
Action sequences use basic QTE with low penalty for failure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
9 Clues: The Secret of Serpent Creek
No adaptive opponent in a casual mystery
The Wolf Among Us
Fables inhabitants follow scripted roles with no adaptive modelling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
9 Clues: The Secret of Serpent Creek
Object and clue locations hidden until found
The Wolf Among Us
Investigation choices partially obscure which evidence matters
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
9 Clues: The Secret of Serpent Creek
Working through puzzles and deductions is the loop
The Wolf Among Us
Scene order and evidence collection allow minor optimisation of deduction paths
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
