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.

Execution · Practiced Mastery
An action adventure rewarding combat timing against scripted boss patterns.

Optimization · Practiced Mastery
Remake of the original Yakuza following Kiryu's return to Kamurocho.
God of War Ragnarok leans Execution (Practiced Mastery); Yakuza Kiwami leans Optimization (Practiced Mastery).
God of War Ragnarok leans a little harder on execution, though the gap is small.
God of War Ragnarok
Parry timing and combo execution in combat
Yakuza Kiwami
Brawling combos and dodges are forgiving but present.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
God of War Ragnarok
Bosses use fixed movesets
Yakuza Kiwami
Majima ambushes are scripted, not adaptive.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
God of War Ragnarok
Negligible randomness
Yakuza Kiwami
Minor randomness in encounters and minigames.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
God of War Ragnarok
Build choices and moveset mastery solve bosses
Yakuza Kiwami
Style upgrades, heat moves and gear 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.
