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
A precise action RPG about learning fixed boss patterns through punishing repetition.

Execution · Practiced Mastery
A stance-action RPG carried by ki-pulse timing and loot build optimization.
Dark Souls leans Execution (Practiced Mastery); Nioh leans Execution (Practiced Mastery).
Nioh leans a little harder on execution, though the gap is small.
Dark Souls
Timing dodges and stamina control define every encounter.
Nioh
Stance and ki-pulse timing demand inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Souls
Bosses run fixed scripted movesets; not adaptive.
Nioh
Scripted enemies
Nioh leans a little harder on variance, though the gap is small.
Dark Souls
Minor drop-rate randomness; otherwise deterministic world.
Nioh
Loot affix rolls
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Souls
Builds, routes, and boss patterns are fully learnable.
Nioh
Build crafting and stance routing reward planning
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.
