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
Underwater dogfighting testing piloting and aim through scripted missions.

Execution · Pure Mechanics
An open-world extreme sports game about carving ski, snowboard, and wingsuit lines down the Alps.
AquaNox leans Execution (Practiced Mastery); Steep leans Execution (Pure Mechanics).
Steep leans a little harder on execution, though the gap is small.
AquaNox
Six-degree underwater dogfighting demands piloting and aim
Steep
Landing tricks and threading lines at speed is hands-first
AquaNox leans a little harder on reads, though the gap is small.
AquaNox
Mission enemies attack on fixed scripts
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.
AquaNox
Missions play out identically each attempt
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.
AquaNox
Ship loadout and weapon choice add modest planning
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.
