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
Nintendo's branching rail shooter where score medals demand perfected routes.

Execution · Practiced Mastery
Movement execution and route optimisation through a fixed, mappable planet.
Star Fox 64 leans Execution (Practiced Mastery); Super Metroid leans Execution (Practiced Mastery).
Star Fox 64 leans a little harder on execution, though the gap is small.
Star Fox 64
Rail-shooter aim, barrel rolls, and boost timing are everything
Super Metroid
Wall-jumps, shinesparks and boss dodges demand precise inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Star Fox 64
Entirely scripted bosses and waves
Super Metroid
Bosses cycle fixed patterns, never adapting
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Star Fox 64
Fully deterministic once routes are known
Super Metroid
Item and route knowledge is fixed once discovered
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Star Fox 64
Medal scores and route branches reward total memorization
Super Metroid
Sequence-breaking route optimisation is the enduring meta-game
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.
