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
A narrative-driven horror walk through a Victorian slaughterhouse engine, lighter on systems than its predecessor.

Variance · Systems & Chaos
Map-and-compass navigation through hidden dangers on a hostile mountain.
Amnesia: A Machine for Pigs leans Optimization (Systems & Chaos); Kholat leans Variance (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Amnesia: A Machine for Pigs
Walking and lever-pulling demand essentially nothing physical
Kholat
Walking the mountain takes no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Amnesia: A Machine for Pigs
Manpigs are scripted set-dressing, rarely a true threat
Kholat
The presence stalks on randomised triggers, not a mind
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Amnesia: A Machine for Pigs
First-run unknowns are the whole experience; spoilers defuse it
Kholat
Navigating by map coordinates with hidden danger zones
Amnesia: A Machine for Pigs leans a little harder on optimization, though the gap is small.
Amnesia: A Machine for Pigs
Light puzzles and routes are trivially solvable on repeat
Kholat
Landmark navigation and route memory converge with repetition
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.
