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.

Execution · Light / Casual
A first-person horror about a journalist investigating an asylum.

Execution · Light / Casual
A puzzle horror game about learning trap solutions through trial and error.
Outlast leans Execution (Light / Casual); The Witch's House MV leans Execution (Light / Casual).
Outlast leans a little harder on execution, though the gap is small.
Outlast
Running, hiding, and camera use.
The Witch's House MV
occasional quick reactions to avoid death traps
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Outlast
Enemies follow scripts.
The Witch's House MV
no adaptive opponent, puzzle-driven horror
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Outlast
Mild patrol variance.
The Witch's House MV
some trial-and-error trap randomness
Outlast leans a little harder on optimization, though the gap is small.
Outlast
Battery and route planning shallow.
The Witch's House MV
learning correct puzzle solutions
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.
