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 branching story that tests choice exploration more than any skill.

Execution · Light / Casual
Branching interactive thriller where QTE choices decide who survives the Origami Killer case.
Detroit: Become Human leans Optimization (Light / Casual); Heavy Rain leans Execution (Light / Casual).
Heavy Rain leans a little harder on execution, though the gap is small.
Detroit: Become Human
Quick-time events demand only basic reaction 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.
Detroit: Become Human
Branching script, no adaptive adversary
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.
Detroit: Become Human
Branch consequences are hidden information until explored
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.
Detroit: Become Human
Flowchart completion is a light solvable puzzle
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.
