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.

Optimization · Practiced Mastery
The genre-defining 3D open-world crime game set in Liberty City.

Execution · Practiced Mastery
A gleefully absurd open-world crime game where the Saints conquer Steelport as celebrity gangsters.
Grand Theft Auto III leans Optimization (Practiced Mastery); Saints Row: The Third leans Execution (Practiced Mastery).
Saints Row: The Third leans a little harder on execution, though the gap is small.
Grand Theft Auto III
Driving and clunky gunplay set a modest physical bar
Saints Row: The Third
Generous shooting and driving keep the skill bar moderate
Saints Row: The Third leans a little harder on reads, though the gap is small.
Grand Theft Auto III
Enemies are scripted; nothing models the player
Saints Row: The Third
Enemy syndicates never adapt to you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto III
Pedestrian and traffic chaos lightly randomises encounters
Saints Row: The Third
Sandbox mayhem injects light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto III
Mission routing and city knowledge are learnable systems
Saints Row: The Third
Upgrade trees and city-takeover income are straightforwardly maximised
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.
