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.

Execution · Light / Casual
Branching interactive thriller where QTE choices decide who survives the Origami Killer case.
Call of Cthulhu leans Optimization (Light / Casual); Heavy Rain leans Execution (Light / Casual).
Heavy Rain leans a little harder on execution, though the gap is small.
Call of Cthulhu
light stealth timing, mostly minor
Heavy Rain
QTE prompts under tension
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
Heavy Rain
No adaptive opposition
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
Heavy Rain
First-run uncertainty about consequences
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Cthulhu
stat allocation lightly solvable
Heavy Rain
Branch knowledge fully solves outcomes
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.
