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 · Pure Mechanics
A first-person cyberpunk slasher where everything dies in one hit, including you.

Execution · Practiced Mastery
Punishing platforming execution over learnable boss orders and part builds.
Ghostrunner leans Execution (Pure Mechanics); Mega Man X6 leans Execution (Practiced Mastery).
Ghostrunner leans a little harder on execution, though the gap is small.
Ghostrunner
One-hit-death parkour and slashing demand near-perfect inputs
Mega Man X6
Cruel platforming and boss windows demand frame-tight inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Ghostrunner
Enemy placements are fixed
Mega Man X6
Bosses are fixed pattern sets
Mega Man X6 leans a little harder on variance, though the gap is small.
Ghostrunner
Deterministic levels
Mega Man X6
The Nightmare System shuffles level hazards between runs
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Ghostrunner
Route planning and enemy-order solutions define fast clears
Mega Man X6
Weapon orders, armor parts and route knowledge are essential
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.
