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

Execution · Practiced Mastery
Flight school score-attack where smooth control of quirky aircraft earns medals.

Execution · Pure Mechanics
An open-world extreme sports game about carving ski, snowboard, and wingsuit lines down the Alps.
Pilotwings 64 leans Execution (Practiced Mastery); Steep leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Pilotwings 64
Precise stick control of gyrocopter and jetpack
Steep
Landing tricks and threading lines at speed is hands-first
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Pilotwings 64
No opposition, only score targets
Steep
The mountain never adapts to you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Pilotwings 64
Courses fully fixed
Steep
Fixed terrain, deterministic physics
Pilotwings 64 leans a little harder on optimization, though the gap is small.
Pilotwings 64
Optimal lines and landings reward study
Steep
Line choice and trick scoring math reward study
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.
