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
The notoriously demanding side-scrolling Zelda built on tight sword duels and RPG levelling.
Dark Souls leans Execution (Practiced Mastery); Zelda II: The Adventure of Link leans Execution (Practiced Mastery).
Dark Souls leans a little harder on execution, though the gap is small.
Dark Souls
Timing dodges and stamina control define every encounter.
Zelda II: The Adventure of Link
Precise sword spacing, shield stabs, brutal platforming
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.
Zelda II: The Adventure of Link
Ironknuckles feint but follow fixed logic
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Souls
Minor drop-rate randomness; otherwise deterministic world.
Zelda II: The Adventure of Link
Layouts fixed, little hidden randomness
Dark Souls leans a little harder on optimization, though the gap is small.
Dark Souls
Builds, routes, and boss patterns are fully learnable.
Zelda II: The Adventure of Link
XP routing, spell use, palace order 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.
