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
Mastering the double-barrel shotgun's rhythm while navigating scripted enemy ambushes across dense urban maps.

Execution · Practiced Mastery
A marble-shooter testing aim and timing to match advancing colored spheres.
Doom II: Hell on Earth leans Execution (Pure Mechanics); Luxor 3 leans Execution (Practiced Mastery).
Doom II: Hell on Earth leans a little harder on execution, though the gap is small.
Doom II: Hell on Earth
Super Shotgun and movement timing demand precise motor execution
Luxor 3
Aiming and timing shots at moving spheres is the core
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Doom II: Hell on Earth
All enemies are scripted; no opponent models the player
Luxor 3
Solo - no opponent to predict
Luxor 3 leans a little harder on variance, though the gap is small.
Doom II: Hell on Earth
Ambush placements are hidden until triggered on first run
Luxor 3
Sphere color sequences add randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Doom II: Hell on Earth
Learning enemy placement and resource routes reduces every encounter
Luxor 3
Power-up usage and chain planning improve scores
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.
