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

Execution · Light / Casual
A casual licensed action game testing little beyond light co-op coordination.

Execution · Light / Casual
Branching interactive thriller where QTE choices decide who survives the Origami Killer case.
Harry Potter and the Goblet of Fire 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.
Harry Potter and the Goblet of Fire
Simple co-op spell casting with generous timing
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.
Harry Potter and the Goblet of Fire
Enemies are fixed waves, no adaptation
Heavy Rain
No adaptive opposition
Heavy Rain leans a little harder on variance, though the gap is small.
Harry Potter and the Goblet of Fire
Collectible bean locations are fixed
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.
Harry Potter and the Goblet of Fire
Light card collection and spell upgrade choices
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.
