head to head
Yakuza 0 asks more than Grand Theft Auto V, and the gap is optimization.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.

Optimization · Practiced Mastery
A brawler RPG mixing style-switch combat with business-routing optimization.
Grand Theft Auto V leans Execution (Practiced Mastery); Yakuza 0 leans Optimization (Practiced Mastery).
Grand Theft Auto V leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Yakuza 0
Brawler combat with style switching
Grand Theft Auto V leans a little harder on reads, though the gap is small.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
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 V
Some mission and lobby randomness.
Yakuza 0
Minor drop randomness
Yakuza 0 leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
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.
