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 point-and-click adventure where inventory puzzle logic is the whole challenge.

Optimization · Light / Casual
A branching story that tests choice exploration more than any skill.
Broken Sword: The Smoking Mirror leans Optimization (Light / Casual); Detroit: Become Human leans Optimization (Light / Casual).
Detroit: Become Human leans a little harder on execution, though the gap is small.
Broken Sword: The Smoking Mirror

Detroit: Become Human
Branching script, no adaptive adversary
Detroit: Become Human leans a little harder on variance, though the gap is small.
Broken Sword: The Smoking Mirror
no meaningful randomness
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.
Broken Sword: The Smoking Mirror
item puzzle logic is solvable
Detroit: Become Human
Flowchart completion is a light solvable puzzle
