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.

Variance · Light / Casual
A narrative thriller testing whether you can untangle scripted unreliable memories.

Optimization · Light / Casual
A branching story that tests choice exploration more than any skill.
Alfred Hitchcock: Vertigo leans Variance (Light / Casual); Detroit: Become Human leans Optimization (Light / Casual).
Detroit: Become Human leans a little harder on execution, though the gap is small.
Alfred Hitchcock: Vertigo
Light interaction in a narrative framework
Detroit: Become Human
Quick-time events demand only basic reaction timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Alfred Hitchcock: Vertigo
Characters follow a script, not your behaviour
Detroit: Become Human
Branching script, no adaptive adversary
Alfred Hitchcock: Vertigo leans a little harder on variance, though the gap is small.
Alfred Hitchcock: Vertigo
Unreliable memories hide the true sequence of events
Detroit: Become Human
Branch consequences are hidden information until explored
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Alfred Hitchcock: Vertigo
Cross-checking timelines is a fixed solvable puzzle
Detroit: Become Human
Flowchart completion is a light solvable puzzle
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.
