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 · Practiced Mastery
Survival horror where you fight ghosts by photographing them with a cursed camera.

Optimization · Pure Optimization
A psychological horror experience where puzzle knowledge and avoidance routing matter more than combat skill.
Fatal Frame leans Optimization (Practiced Mastery); Silent Hill 2 (2001) leans Optimization (Pure Optimization).
Fatal Frame leans a little harder on execution, though the gap is small.
Fatal Frame
Camera framing and shutter timing on ghosts
Silent Hill 2 (2001)
Clunky combat is intentional; survival over precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fatal Frame
Ghosts wander but never adapt to you
Silent Hill 2 (2001)
Monsters follow simple fixed behaviours, never model the player
Fatal Frame leans a little harder on variance, though the gap is small.
Fatal Frame
Ghost appearances feel unpredictable until learned
Silent Hill 2 (2001)
Some item placements are unknown first time; fixed thereafter
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fatal Frame
Item routing, film economy, learning ghost patterns
Silent Hill 2 (2001)
Puzzle solutions, route knowledge and weapon use 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.
