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
Balletic side-scrolling shooter about chaining stylish slow-motion gun acrobatics.

Execution · Practiced Mastery
Nintendo's branching rail shooter where score medals demand perfected routes.
My Friend Pedro leans Execution (Practiced Mastery); Star Fox 64 leans Execution (Practiced Mastery).
Star Fox 64 leans a little harder on execution, though the gap is small.
My Friend Pedro
Slow-motion acrobatic gunplay rewards precise control
Star Fox 64
Rail-shooter aim, barrel rolls, and boost timing are everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
My Friend Pedro
Enemies are static placements
Star Fox 64
Entirely scripted bosses and waves
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
My Friend Pedro
Deterministic levels
Star Fox 64
Fully deterministic once routes are known
Star Fox 64 leans a little harder on optimization, though the gap is small.
My Friend Pedro
Score-chasing optimal routes and trick chains
Star Fox 64
Medal scores and route branches reward total memorization
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.
