head to head
Penumbra: Black Plague asks more than L.A. Noire, and the gap is optimization.

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

Optimization · Systems & Chaos
Frictional's defenseless first-person horror where you solve physics puzzles while hiding from the infected.
L.A. Noire leans Optimization (Systems & Chaos); Penumbra: Black Plague 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
Penumbra: Black Plague
Physics-grab interactions need only basic mouse control
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
Penumbra: Black Plague
Infected patrol on scripts; hiding beats them every time
Penumbra: Black Plague leans a little harder on variance, though the gap is small.
L.A. Noire
Interrogation tells and clues hidden until discovered
Penumbra: Black Plague
Unknown layouts, scares, and patrols on a blind run
Penumbra: Black Plague leans clearly harder on optimization.
L.A. Noire
Evidence chains and question choices have fixed correct answers
Penumbra: Black Plague
Physics puzzles and evasion routes are fully solvable
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.
