head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, 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
The 1986 original that defined exploration-driven, secret-riddled platforming.
Fatal Frame III: The Tormented leans Optimization (Practiced Mastery); Metroid 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
Metroid
stiff NES jumps and tough enemy contact
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fatal Frame III: The Tormented
Ghosts attack on scripted patterns
Metroid
creatures follow fixed movement
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
Metroid
unmarked secrets and bombable blocks hide the map
Fatal Frame III: The Tormented leans a little harder on optimization, though the gap is small.
Fatal Frame III: The Tormented
Camera upgrades and ghost patterns fully converge
Metroid
route and item knowledge transforms the game
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.
