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
Capcom's infamously punishing arcade platformer that makes you beat it twice for the real ending.

Execution · Practiced Mastery
Neon top-down massacre where each floor is a one-mistake execution puzzle.
Ghosts 'n Goblins leans Execution (Pure Mechanics); Hotline Miami leans Execution (Practiced Mastery).
Ghosts 'n Goblins leans a little harder on execution, though the gap is small.
Ghosts 'n Goblins
Committed jumps and pixel-precise throws, no mercy
Hotline Miami
One-hit-death rooms demand flawless fast inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Ghosts 'n Goblins
Enemy spawns are scripted
Hotline Miami
Enemies are dumb scripted reactors
Hotline Miami leans a little harder on variance, though the gap is small.
Ghosts 'n Goblins
Red Arremer movement adds slight noise
Hotline Miami
Slight enemy behavior wobble between restarts
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Ghosts 'n Goblins
Weapon choice and route memorisation are mandatory
Hotline Miami
Route planning and mask choice per floor
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.
