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 first-person runner testing reflexive timing at extreme speed.
DOOM (2016) leans Execution (Pure Mechanics); Fotonica leans Execution (Pure Mechanics).
Fotonica leans a little harder on execution, though the gap is small.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
Fotonica
One-button timing at extreme speed defines everything
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Fotonica
Solo runner, no opponent to predict
Fotonica leans a little harder on variance, though the gap is small.
DOOM (2016)
Minimal encounter randomness.
Fotonica
Tracks are fixed once learned, little randomness
DOOM (2016) leans a little harder on optimization, though the gap is small.
DOOM (2016)
Rune and weapon mod picks meaningful.
Fotonica
Memorizing track geometry plans optimal lines
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.
