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.

Execution · Twitch Chaos
A timed perception test of finding hidden objects in cluttered crime scenes.

Execution · Light / Casual
A first-person horror about a journalist investigating an asylum.
Criminal Case leans Execution (Twitch Chaos); Outlast leans Execution (Light / Casual).
Criminal Case leans a little harder on execution, though the gap is small.
Criminal Case
Spotting objects quickly under a timer is the whole test
Outlast
Running, hiding, and camera use.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Criminal Case
No opponent; suspects are static puzzle pieces
Outlast
Enemies follow scripts.
Criminal Case leans a little harder on variance, though the gap is small.
Criminal Case
Object placements are unknown per scene until memorised
Outlast
Mild patrol variance.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Criminal Case
Scene layouts converge to memorised positions on replays
Outlast
Battery and route planning shallow.
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.
