head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

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

Optimization · Systems & Chaos
A scripted horror adventure that tests puzzle-solving and route knowledge, not nerves alone.
L.A. Noire leans Optimization (Systems & Chaos); Paper Lily: Chapter 1 leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
L.A. Noire
Light shooting and driving, very forgiving
Paper Lily: Chapter 1
Light chase sequences are the only dexterity demand
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
Paper Lily: Chapter 1
Scripted encounters with no adaptive adversary
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
Paper Lily: Chapter 1
Unknown puzzle solutions and surprises until the route is learned
Paper Lily: Chapter 1 leans a little harder on optimization, though the gap is small.
L.A. Noire
Evidence chains and question choices have fixed correct answers
Paper Lily: Chapter 1
Solving puzzles and finding the correct paths is the game
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.
