head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Practiced Mastery
A feudal-Japan open-world RPG balancing stealth routing against build progression.

Optimization · Practiced Mastery
A brawler RPG mixing style-switch combat with business-routing optimization.
Assassin's Creed Shadows 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.
Assassin's Creed Shadows
Dual protagonists reward timing, still forgiving.
Yakuza 0
Brawler combat with style switching
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Shadows
Enemy AI scripted, not adaptive.
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.
Assassin's Creed Shadows
Loot and seasonal conditions lightly randomized.
Yakuza 0
Minor drop randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Shadows
Builds, gear, and stealth routes solvable.
Yakuza 0
Skill tree, business mini-game routing
