head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

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

Optimization · Practiced Mastery
Slapstick physics puzzler about hauling a wobbly ragdoll through dreamscapes.
Grand Theft Auto III leans Optimization (Practiced Mastery); Human: Fall Flat 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.
Grand Theft Auto III
Driving and clunky gunplay set a modest physical bar
Human: Fall Flat
Wrestling floppy physics limbs is the joke
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto III
Enemies are scripted; nothing models the player
Human: Fall Flat
No adversary, only wobbly geometry
Grand Theft Auto III leans a little harder on variance, though the gap is small.
Grand Theft Auto III
Pedestrian and traffic chaos lightly randomises encounters
Human: Fall Flat
Physics jank adds slapstick unpredictability
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
Human: Fall Flat
Puzzle solutions and shortcut discovery
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.
