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

Optimization · Practiced Mastery
Horror about photographing ghosts at the last possible second inside a recurring dream manor.

Optimization · Practiced Mastery
A first-person haunted-house survival game solved by crafting optimisation and scripted-enemy routing.
Fatal Frame III: The Tormented leans Optimization (Practiced Mastery); Resident Evil 7: Biohazard leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fatal Frame III: The Tormented
Fatal Frame shutter timing rewards held-nerve precision
Resident Evil 7: Biohazard
First-person aiming and blocking under Molded pressure matters
Resident Evil 7: Biohazard leans a little harder on reads, though the gap is small.
Fatal Frame III: The Tormented
Ghosts attack on scripted patterns
Resident Evil 7: Biohazard
Family AI follows scripted stalker scripts, never adapts to you
Fatal Frame III: The Tormented leans a little harder on variance, though the gap is small.
Fatal Frame III: The Tormented
Ghost spawns and dream-house layout surprise first run
Resident Evil 7: Biohazard
Limited item locations are unknown on first visits
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fatal Frame III: The Tormented
Camera upgrades and ghost patterns fully converge
Resident Evil 7: Biohazard
Resource crafting, tape management and route sequencing are 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.
