head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Pure Mechanics
Push-forward arena FPS where movement and aim are the whole game.

Execution · Pure Mechanics
Pure jump timing over fully fixed, memorisable levels.
DOOM (2016) leans Execution (Pure Mechanics); Super Mario Bros. 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.
Super Mario Bros.
Perfect inputs trivialise momentum jumps over fixed hazards
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Super Mario Bros.
Goombas walk left forever - nothing to predict
DOOM (2016) leans a little harder on variance, though the gap is small.
DOOM (2016)
Minimal encounter randomness.
Super Mario Bros.
Every level is identical on every run
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.
Super Mario Bros.
Level memorisation and warp routing are fully solvable
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.
