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.

Optimization · Practiced Mastery
A meta puzzle box testing curiosity and one-time discovery more than any repeatable skill.
L.A. Noire leans Optimization (Systems & Chaos); Pony Island leans Optimization (Practiced Mastery).
Pony Island leans a little harder on execution, though the gap is small.
L.A. Noire
Light shooting and driving, very forgiving
Pony Island
Light arcade hopping segments with low demands
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
Pony Island
The devil's tricks are authored scripts, not adaptation
L.A. Noire leans a little harder on variance, though the gap is small.
L.A. Noire
Interrogation tells and clues hidden until discovered
Pony Island
Meta twists are hidden information that spend on first reveal
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
L.A. Noire
Evidence chains and question choices have fixed correct answers
Pony Island
Code-tinkering puzzles have fixed discoverable solutions
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.
