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 first-person horror about exploring a haunted Prussian castle.

Execution · Light / Casual
Branching interactive thriller where QTE choices decide who survives the Origami Killer case.
Amnesia: The Dark Descent leans Optimization (Light / Casual); Heavy Rain leans Execution (Light / Casual).
Heavy Rain leans a little harder on execution, though the gap is small.
Amnesia: The Dark Descent
Stealth and hiding, low demand.
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.
Amnesia: The Dark Descent
Monsters follow scripted patrols.
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.
Amnesia: The Dark Descent
Minor encounter variation.
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.
Amnesia: The Dark Descent
Oil and sanity management is shallow.
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.
