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 survival horror shooter aboard a storm-tossed whaler where the rolling deck fights your aim as much as the parasites do.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Cold Fear leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Cold Fear leans a little harder on execution, though the gap is small.
Cold Fear
Aiming on a storm-rocked ship deck is the signature test
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cold Fear
Exocels and mercenaries run fixed AI scripts
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Cold Fear leans a little harder on variance, though the gap is small.
Cold Fear
Some unknown ambushes on a first playthrough
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Cold Fear
Weak-point targeting and ammo economy reward learned play
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
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.
