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

Execution · Pure Mechanics
The N64 entry whose boost-or-survive health gamble layers routing decisions onto raw speed control.
DOOM (2016) leans Execution (Pure Mechanics); F-Zero X 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.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
F-Zero X
Sixty-frame control of thirty machines at top speed
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.
F-Zero X
Rival AI is non-adaptive
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.
F-Zero X
X Cup random tracks are a minor mode
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Rune and weapon mod picks meaningful.
F-Zero X
Boost-health tradeoffs and shortcuts reward routing
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.
