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 · Systems & Chaos
Uncovering hidden item-puzzle solutions along a fixed time-travel story path.
L.A. Noire leans Optimization (Systems & Chaos); The Silent Age leans Optimization (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
The Silent Age
Pointing and clicking carries no physical test
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
The Silent Age
A fixed story; nothing adapts
L.A. Noire leans a little harder on variance, though the gap is small.
L.A. Noire
Interrogation tells and clues hidden until discovered
The Silent Age
Puzzle solutions are hidden information until discovered
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
The Silent Age
Item-combination logic converges to a single known path
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.
