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.

Optimization · Light / Casual
An underwater sci-fi horror about consciousness and identity.
Heavy Rain leans Execution (Light / Casual); SOMA leans Optimization (Light / Casual).
Heavy Rain leans a little harder on execution, though the gap is small.
Heavy Rain
QTE prompts under tension
SOMA
Light stealth, gentle inputs.
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
SOMA
Creatures follow scripts.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Heavy Rain
First-run uncertainty about consequences
SOMA
Some hiding spot variation.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Heavy Rain
Branch knowledge fully solves outcomes
SOMA
Few systems 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.
