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

Execution · Practiced Mastery
A janky stealth-survival detour that tests patience more than skill.

Optimization · Practiced Mastery
The genre-defining 3D open-world crime game set in Liberty City.
Escape Dead Island leans Execution (Practiced Mastery); Grand Theft Auto III 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.
Escape Dead Island
Stealth takedowns and clumsy melee ask modest timing
Grand Theft Auto III
Driving and clunky gunplay set a modest physical bar
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Escape Dead Island
Zombies follow simple aggro scripts
Grand Theft Auto III
Enemies are scripted; nothing models the player
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Escape Dead Island
Unreliable-narrator twists hide story, not mechanics
Grand Theft Auto III
Pedestrian and traffic chaos lightly randomises encounters
Grand Theft Auto III leans a little harder on optimization, though the gap is small.
Escape Dead Island
Route and resource choices barely resist solving
Grand Theft Auto III
Mission routing and city knowledge are learnable systems
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.
