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 · Systems & Chaos
1940s detective procedural built around crime scenes and reading scripted interrogation tells.

Variance · Systems & Chaos
Navigating unseen spaces by sound while rationing the noise that summons danger.
L.A. Noire leans Optimization (Systems & Chaos); Perception leans Variance (Systems & Chaos).
L.A. Noire leans a little harder on execution, though the gap is small.
L.A. Noire
Light shooting and driving, very forgiving
Perception
Echolocation taps and walking ask little of the hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
L.A. Noire
Suspects follow fixed scripts, never adapt
Perception
The Presence triggers on scripted noise thresholds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
L.A. Noire
Interrogation tells and clues hidden until discovered
Perception
Blind navigation makes layouts hidden information at first
L.A. Noire leans a little harder on optimization, though the gap is small.
L.A. Noire
Evidence chains and question choices have fixed correct answers
Perception
Managing noise and learning routes converges quickly
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.
