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 · Practiced Mastery
A rail shooter testing reflex execution against fully memorisable enemy waves.
DOOM (2016) leans Execution (Pure Mechanics); Star Fox leans Execution (Practiced Mastery).
DOOM (2016) leans a little harder on execution, though the gap is small.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
Star Fox
Dodging, shooting and barrel rolls on rails demand reflexes
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Star Fox
Every enemy wave is a fixed scripted pattern
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.
Star Fox
Routes and spawns are deterministic per path
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.
Star Fox
Memorising wave patterns and route choices for score
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.
