head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Light / Casual
A pack-in 3D platformer celebrating PlayStation history.

Execution · Light / Casual
Branching interactive thriller where QTE choices decide who survives the Origami Killer case.
Astro's Playroom leans Execution (Light / Casual); Heavy Rain leans Execution (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Astro's Playroom
Very forgiving platforming
Heavy Rain
QTE prompts under tension
Astro's Playroom leans a little harder on reads, though the gap is small.
Astro's Playroom
Scripted enemies
Heavy Rain
No adaptive opposition
Heavy Rain leans a little harder on variance, though the gap is small.
Astro's Playroom
Static levels
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.
Astro's Playroom
Collectible completion
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.
