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

Execution · Practiced Mastery
Robot-dinosaur hunting that rewards weak-point study and ranged precision.

Optimization · Practiced Mastery
Remake of the original Yakuza following Kiryu's return to Kamurocho.
Horizon Zero Dawn leans Execution (Practiced Mastery); Yakuza Kiwami 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.
Horizon Zero Dawn
Bow aiming and dodge timing matter.
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.
Horizon Zero Dawn
Machines follow fixed patterns, not adapting.
Yakuza Kiwami
Majima ambushes are scripted, not adaptive.
Horizon Zero Dawn leans a little harder on variance, though the gap is small.
Horizon Zero Dawn
Some loot and patrol randomness.
Yakuza Kiwami
Minor randomness in encounters and minigames.
Yakuza Kiwami leans a little harder on optimization, though the gap is small.
Horizon Zero Dawn
Weak points, traps, builds fully solvable.
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.
