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
Tests visual search and light puzzle solving through a scripted mystery.

Optimization · Systems & Chaos
1940s detective procedural built around crime scenes and reading scripted interrogation tells.
Dark Arcana: The Carnival leans Optimization (Systems & Chaos); L.A. Noire leans Optimization (Systems & Chaos).
L.A. Noire leans a little harder on execution, though the gap is small.
Dark Arcana: The Carnival
Clicking hidden objects needs no dexterity
L.A. Noire
Light shooting and driving, very forgiving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Arcana: The Carnival
Solo with entirely scripted story beats
L.A. Noire
Suspects follow fixed scripts, never adapt
L.A. Noire leans a little harder on variance, though the gap is small.
Dark Arcana: The Carnival
Object locations are unknown until spotted
L.A. Noire
Interrogation tells and clues hidden until discovered
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Arcana: The Carnival
Minigames and scene logic have fixed solutions
L.A. Noire
Evidence chains and question choices have fixed correct answers
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.
