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

Execution · Pure Mechanics
Capcom's infamously punishing arcade platformer that makes you beat it twice for the real ending.
Ghostrunner leans Execution (Pure Mechanics); Ghosts 'n Goblins 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.
Ghostrunner
One-hit-death parkour and slashing demand near-perfect inputs
Ghosts 'n Goblins
Committed jumps and pixel-precise throws, no mercy
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
Ghosts 'n Goblins
Enemy spawns are scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Ghostrunner
Deterministic levels
Ghosts 'n Goblins
Red Arremer movement adds slight noise
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
Ghosts 'n Goblins
Weapon choice and route memorisation are mandatory
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.
