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

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

Optimization · Practiced Mastery
A brawler RPG mixing style-switch combat with business-routing optimization.
Grand Theft Auto III leans Optimization (Practiced Mastery); Yakuza 0 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
Yakuza 0
Brawler combat with style switching
Yakuza 0 leans a little harder on reads, though the gap is small.
Grand Theft Auto III
Enemies are scripted; nothing models the player
Yakuza 0
Scripted enemies
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
Yakuza 0
Minor drop randomness
Yakuza 0 leans a little harder on optimization, though the gap is small.
Grand Theft Auto III
Mission routing and city knowledge are learnable systems
Yakuza 0
Skill tree, business mini-game routing
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.
