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
A test of fast, precise shooting and map navigation against scripted but relentless enemies.

Execution · Pure Mechanics
A rail light-gun shooter testing aim and reaction against scripted horrors.
Doom (1993) leans Execution (Pure Mechanics); Silent Hill: The Arcade leans Execution (Pure Mechanics).
Doom (1993) leans a little harder on execution, though the gap is small.
Doom (1993)
Precise movement and shooting against relentless enemy pressure
Silent Hill: The Arcade
Light-gun aiming and reaction speed are core
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Doom (1993)
Enemies follow scripted patrol and attack patterns, not adaptive
Silent Hill: The Arcade
Enemies appear on fixed rails, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Doom (1993)
Enemy placement is fixed but unknown on first run through levels
Silent Hill: The Arcade
Some enemy spawn variation adds chaos
Doom (1993) leans a little harder on optimization, though the gap is small.
Doom (1993)
Level routing and resource management determine survival efficiency
Silent Hill: The Arcade
Learning enemy spawn spots rewards memorization
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.
