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

Optimization · Practiced Mastery
A top-down handheld GTA built around missions and a buy-low-sell-high drug economy.
Fatal Frame leans Optimization (Practiced Mastery); Grand Theft Auto: Chinatown Wars 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
Camera framing and shutter timing on ghosts
Grand Theft Auto: Chinatown Wars
Touch minigames and top-down driving need modest dexterity
Fatal Frame leans a little harder on reads, though the gap is small.
Fatal Frame
Ghosts wander but never adapt to you
Grand Theft Auto: Chinatown Wars
No adaptive opponents anywhere
Fatal Frame leans a little harder on variance, though the gap is small.
Fatal Frame
Ghost appearances feel unpredictable until learned
Grand Theft Auto: Chinatown Wars
Drug market prices fluctuate semi-randomly
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
Grand Theft Auto: Chinatown Wars
The drug-trading economy is the real solvable 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.
