head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

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

Execution · Pure Mechanics
Mastering the double-barrel shotgun's rhythm while navigating scripted enemy ambushes across dense urban maps.
Doom (1993) leans Execution (Pure Mechanics); Doom II: Hell on Earth 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 (1993)
Precise movement and shooting against relentless enemy pressure
Doom II: Hell on Earth
Super Shotgun and movement timing demand precise motor execution
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
Doom II: Hell on Earth
All enemies are scripted; no opponent models the player
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
Doom II: Hell on Earth
Ambush placements are hidden until triggered on first run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Doom (1993)
Level routing and resource management determine survival efficiency
Doom II: Hell on Earth
Learning enemy placement and resource routes reduces every encounter
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.
