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
Push-forward arena FPS where movement and aim are the whole game.

Execution · Pure Mechanics
A first-person cyberpunk slasher where everything dies in one hit, including you.
DOOM (2016) leans Execution (Pure Mechanics); Ghostrunner leans Execution (Pure Mechanics).
Ghostrunner leans a little harder on execution, though the gap is small.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
Ghostrunner
One-hit-death parkour and slashing demand near-perfect inputs
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Ghostrunner
Enemy placements are fixed
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Minimal encounter randomness.
Ghostrunner
Deterministic levels
Ghostrunner leans a little harder on optimization, though the gap is small.
DOOM (2016)
Rune and weapon mod picks meaningful.
Ghostrunner
Route planning and enemy-order solutions define fast clears
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.
