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 · Light / Casual
A narrative horror-investigation game where uncovering the mystery outweighs any mechanical challenge.

Optimization · Systems & Chaos
A visual novel first and a light tactics game second, heavy on story.
Call of Cthulhu leans Optimization (Light / Casual); Utawarerumono: Mask of Deception leans Optimization (Systems & Chaos).
Call of Cthulhu leans a little harder on execution, though the gap is small.
Call of Cthulhu
light stealth timing, mostly minor
Utawarerumono: Mask of Deception
Optional timing presses on attacks
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Cthulhu
no opponents, narrative investigation
Utawarerumono: Mask of Deception
Enemy AI is scripted and predictable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Cthulhu
skill checks add randomness
Utawarerumono: Mask of Deception
Light combat RNG in a mostly fixed story
Utawarerumono: Mask of Deception leans a little harder on optimization, though the gap is small.
Call of Cthulhu
stat allocation lightly solvable
Utawarerumono: Mask of Deception
Easy SRPG battles solved with basic positioning
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.
