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
Open-world action game where procedurally generated orc captains remember your encounters.
Fatal Frame III: The Tormented leans Optimization (Practiced Mastery); Middle-earth: Shadow of Mordor 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
Middle-earth: Shadow of Mordor
Counter-timing combat and stealth execution
Middle-earth: Shadow of Mordor leans a little harder on reads, though the gap is small.
Fatal Frame III: The Tormented
Ghosts attack on scripted patterns
Middle-earth: Shadow of Mordor
Nemesis orcs remember you but remain mappable scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fatal Frame III: The Tormented
Ghost spawns and dream-house layout surprise first run
Middle-earth: Shadow of Mordor
Procedural captains with hidden strengths and weaknesses
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
Middle-earth: Shadow of Mordor
Intel gathering and exploiting known weaknesses solves fights
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.
