Amnesia: A Machine for PigsvsDon't Knock Twice
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.
Amnesia: A Machine for Pigs
Optimization · Systems & Chaos
A narrative-driven horror walk through a Victorian slaughterhouse engine, lighter on systems than its predecessor.
Don't Knock Twice
Variance · Systems & Chaos
A short horror walk that tests little beyond finding fixed clues under scripted scares.
Amnesia: A Machine for Pigs leans Optimization (Systems & Chaos); Don't Knock Twice leans Variance (Systems & Chaos).
Amnesia: A Machine for PigsDon't Knock Twice
Axis by axis
Execution1 vs 1
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
Don't Knock Twice
Walking and grabbing objects - no dexterity test
Reads0 vs 0
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
Don't Knock Twice
The witch follows scripted triggers, not an adapting mind
Variance4 vs 4
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
Don't Knock Twice
Scares and clue placement are unknown until experienced
Optimization5 vs 4
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
Don't Knock Twice
Puzzle solutions and routes are fixed once learned
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.
