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

Execution · Practiced Mastery
The PS2 sequel escalating Kratos's mythological rampage against the Sisters of Fate.

Execution · Practiced Mastery
The 32-bit X series highlight where Zero becomes fully playable with his own saber-based campaign.
God of War II leans Execution (Practiced Mastery); Mega Man X4 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
God of War II
Faster combat and harder bosses demand sharper hands
Mega Man X4
Dash-jump mobility and Zero's saber combos test hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
God of War II
Entirely scripted opposition
Mega Man X4
Mavericks follow fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
God of War II
Deterministic encounter design
Mega Man X4
Upgrade capsule locations hidden initially
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
God of War II
Magic priorities, upgrades, and boss patterns are learnable
Mega Man X4
Armor parts, weakness order, and X-vs-Zero 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.
