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
Memorising punishing fixed stages and executing precise run-and-gun inputs.
DOOM (2016) leans Execution (Pure Mechanics); Journey to Silius 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.
Journey to Silius
Precise jumps and dodges under NES-hard pressure define it
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Journey to Silius
Every enemy and boss is rigidly scripted
DOOM (2016) leans a little harder on variance, though the gap is small.
DOOM (2016)
Minimal encounter randomness.
Journey to Silius
Identical layouts and spawns every attempt
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.
Journey to Silius
Weapon-energy budgeting and pattern memorisation make clears possible
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.
