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 · Pure Mechanics
A 3D marble-rolling platformer through skyborne courses.

Execution · Pure Mechanics
An open-world extreme sports game about carving ski, snowboard, and wingsuit lines down the Alps.
Marble Skies 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.
Marble Skies
precise marble control through 3D courses
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.
Marble Skies
no opponent, solo time-trial platforming
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.
Marble Skies
fixed level layouts, minimal randomness
Steep
Fixed terrain, deterministic physics
Steep leans a little harder on optimization, though the gap is small.
Marble Skies
route memorization for best times
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.
