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 top-down action shooter testing aim and cover timing in noir gunfights.
DOOM (2016) leans Execution (Pure Mechanics); Milanoir leans Execution (Pure Mechanics).
DOOM (2016) leans a little harder on execution, though the gap is small.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
Milanoir
Twin-stick aiming and cover timing drive firefights
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Demons scripted attack patterns.
Milanoir
Enemies follow scripts, no adaptive prediction
Milanoir leans a little harder on variance, though the gap is small.
DOOM (2016)
Minimal encounter randomness.
Milanoir
Enemy spawn timing adds minor chaos
DOOM (2016) leans a little harder on optimization, though the gap is small.
DOOM (2016)
Rune and weapon mod picks meaningful.
Milanoir
Cover use and weapon choice reward planning
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.
