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.

Optimization · Light / Casual
A point-and-click detective adventure focused on investigation and puzzle-solving.
Detroit: Become Human leans Optimization (Light / Casual); Still Life 2 leans Optimization (Light / Casual).
Detroit: Become Human leans a little harder on execution, though the gap is small.
Detroit: Become Human
Quick-time events demand only basic reaction timing
Still Life 2
no physical skill beyond puzzle interaction
Still Life 2 leans a little harder on reads, though the gap is small.
Detroit: Become Human
Branching script, no adaptive adversary
Still Life 2
no adversarial opponent, investigative narrative
Detroit: Become Human leans a little harder on variance, though the gap is small.
Detroit: Become Human
Branch consequences are hidden information until explored
Still Life 2
minimal randomness, fixed puzzle solutions
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
Still Life 2
puzzle logic solving is the main systems layer
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.
