head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

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.

Execution · Practiced Mastery
The original top-down crime sandbox where you rack up points causing mayhem across three cities.
Cold Fear leans Execution (Practiced Mastery); Grand Theft Auto leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Cold Fear
Aiming on a storm-rocked ship deck is the signature test
Grand Theft Auto
Twitchy top-down driving and shooting under police pressure
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
Cops follow simple scripts; nothing adapts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cold Fear
Some unknown ambushes on a first playthrough
Grand Theft Auto
Chaotic traffic and wanted-level escalation surprise players
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cold Fear
Weak-point targeting and ammo economy reward learned play
Grand Theft Auto
Score targets reward learning missions and city layouts
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.
