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.

Execution · Light / Casual
Branching interactive thriller where QTE choices decide who survives the Origami Killer case.

Execution · Light / Casual
A collection of short stories about a family's strange deaths.
Heavy Rain leans Execution (Light / Casual); What Remains of Edith Finch leans Execution (Light / Casual).
Heavy Rain leans a little harder on execution, though the gap is small.
Heavy Rain
QTE prompts under tension
What Remains of Edith Finch
Varied vignettes require light input skill.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Heavy Rain
No adaptive opposition
What Remains of Edith Finch
No adversaries.
Heavy Rain leans a little harder on variance, though the gap is small.
Heavy Rain
First-run uncertainty about consequences
What Remains of Edith Finch
Stories are fixed.
Heavy Rain leans a little harder on optimization, though the gap is small.
Heavy Rain
Branch knowledge fully solves outcomes
What Remains of Edith Finch
Little to optimize.
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.
