head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
Split-attention aiming and flying through fixed, memorizable rail-shooter stages.

Execution · Pure Mechanics
An open-world extreme sports game about carving ski, snowboard, and wingsuit lines down the Alps.
Star Fox Zero leans Execution (Pure Mechanics); 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.
Star Fox Zero
Dual-screen aiming while flying is the central demand
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.
Star Fox Zero
Enemy squadrons fly scripted routes
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.
Star Fox Zero
Levels replay identically every run
Steep
Fixed terrain, deterministic physics
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Star Fox Zero
Score routes and medal paths reward memorization
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.
