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

Variance · Systems & Chaos
A horror adventure sequel where a delinquent investigates urban-legend spirits to save his kidnapped sister.
Amnesia: A Machine for Pigs leans Optimization (Systems & Chaos); Spirit Hunter: NG leans Variance (Systems & Chaos).
Amnesia: A Machine for Pigs leans a little harder on execution, though the gap is small.
Amnesia: A Machine for Pigs
Walking and lever-pulling demand essentially nothing physical
Spirit Hunter: NG
Menu-driven investigation; no physical skill ceiling.
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
Spirit Hunter: NG
Spirit behaviour is scripted, never modelling the player.
Spirit Hunter: NG leans a little harder on variance, though the gap is small.
Amnesia: A Machine for Pigs
First-run unknowns are the whole experience; spoilers defuse it
Spirit Hunter: NG
Hidden death triggers and unknown spirit lore dominate first runs.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Amnesia: A Machine for Pigs
Light puzzles and routes are trivially solvable on repeat
Spirit Hunter: NG
Correct evidence and choices are fixed and fully learnable.
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.
