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

Optimization · Systems & Chaos
Frictional's defenseless first-person horror where you solve physics puzzles while hiding from the infected.

Optimization · Systems & Chaos
Planning movement and resource routes across randomised wilderness weather against condition decay.
Penumbra: Black Plague leans Optimization (Systems & Chaos); The Long Dark 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.
Penumbra: Black Plague
Physics-grab interactions need only basic mouse control
The Long Dark
Rifle aim and wolf struggles need minimal twitch
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Penumbra: Black Plague
Infected patrol on scripts; hiding beats them every time
The Long Dark
Wildlife behaves via scripted threat logic, not player modelling
The Long Dark leans a little harder on variance, though the gap is small.
Penumbra: Black Plague
Unknown layouts, scares, and patrols on a blind run
The Long Dark
Blizzard timing, condition decay, and loot spawns are heavily random
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Penumbra: Black Plague
Physics puzzles and evasion routes are fully solvable
The Long Dark
Route planning, calorie budgeting, and item condition management are 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.
