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
A PSP-born GTA prequel adding a business empire system to 1984 Vice City.

Optimization · Practiced Mastery
A narrative action RPG where build planning matters more than reflex execution.
Grand Theft Auto: Vice City Stories leans Optimization (Practiced Mastery); The Witcher 3: Wild Hunt leans Optimization (Practiced Mastery).
Grand Theft Auto: Vice City Stories leans a little harder on execution, though the gap is small.
Grand Theft Auto: Vice City Stories
Driving, aiming, and helicopter handling on a stick
The Witcher 3: Wild Hunt
Combat timing matters but generous dodges forgive sloppy play.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: Vice City Stories
Mission enemies are scripted and predictable
The Witcher 3: Wild Hunt
Enemies use fixed AI behaviours; no adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: Vice City Stories
Mostly fixed missions with light traffic randomness
The Witcher 3: Wild Hunt
Loot rolls and minor combat variance only.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: Vice City Stories
Empire-building business system layers economy onto missions
The Witcher 3: Wild Hunt
Builds, alchemy, and quest routing reward planning.
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.
