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

Execution · Practiced Mastery
A test of 3D movement control with a deep routing layer underneath.

Execution · Practiced Mastery
The notoriously demanding side-scrolling Zelda built on tight sword duels and RPG levelling.
Super Mario 64 leans Execution (Practiced Mastery); Zelda II: The Adventure of Link 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.
Super Mario 64
Perfect analog inputs trivialise precise jumps, dives and wall-kicks
Zelda II: The Adventure of Link
Precise sword spacing, shield stabs, brutal platforming
Zelda II: The Adventure of Link leans a little harder on reads, though the gap is small.
Super Mario 64
Solo platformer - no adaptive opponent anywhere
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.
Super Mario 64
Star locations and level layouts are fixed once seen
Zelda II: The Adventure of Link
Layouts fixed, little hidden randomness
Zelda II: The Adventure of Link leans a little harder on optimization, though the gap is small.
Super Mario 64
Star routing and movement tech form a deep solvable layer
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.
