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.

Execution · Practiced Mastery
A claustrophobic first-person shooter horror game testing precise aim and stamina management under scarce resources.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Cry of Fear leans Execution (Practiced Mastery); Grand Theft Auto V leans Execution (Practiced Mastery).
Cry of Fear leans a little harder on execution, though the gap is small.
Cry of Fear
Fast-paced shooting with limited stamina and scarce ammo demands precision
Grand Theft Auto V
Driving and shooting demand decent inputs.
Grand Theft Auto V leans a little harder on reads, though the gap is small.
Cry of Fear
Enemies follow scripted assault patterns
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Cry of Fear leans a little harder on variance, though the gap is small.
Cry of Fear
Some item locations are unknown on first run
Grand Theft Auto V
Some mission and lobby randomness.
Cry of Fear leans a little harder on optimization, though the gap is small.
Cry of Fear
Weapon selection, safe routing and stamina discipline are optimisable
Grand Theft Auto V
Heists, money loops, builds 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.
