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
Punk action game about an otaku assassin climbing a ranked killer leaderboard.

Execution · Practiced Mastery
Alt-history FPS pivoting between brutal combat and quiet moments.
No More Heroes leans Execution (Practiced Mastery); Wolfenstein: The New Order 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.
No More Heroes
Beam katana clashes and wrestling throws with motion timing
Wolfenstein: The New Order
Dual-wield shooting and movement demand inputs.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
No More Heroes
Assassins are scripted boss fights
Wolfenstein: The New Order
Nazi AI scripted, predictable.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
No More Heroes
Deterministic encounters
Wolfenstein: The New Order
Almost no randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
No More Heroes
Boss pattern learning and money grinding
Wolfenstein: The New Order
Perks and weapon upgrades light.
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.
