head to head
Doom Eternal asks more than DOOM (2016), and the gap is optimization.

Execution · Pure Mechanics
Push-forward arena FPS where movement and aim are the whole game.

Execution · Practiced Mastery
A fast solo FPS where managed aggression and weapon swapping sustain you.
DOOM (2016) leans Execution (Pure Mechanics); Doom Eternal leans Execution (Practiced Mastery).
Doom Eternal leans a little harder on execution, though the gap is small.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
Doom Eternal
Weapon swapping and movement push the hands hard.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Demons scripted attack patterns.
Doom Eternal
Demon AI is scripted, not adaptive.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Minimal encounter randomness.
Doom Eternal
Encounters are designed, not randomised.
Doom Eternal leans clearly harder on optimization.
DOOM (2016)
Rune and weapon mod picks meaningful.
Doom Eternal
Resource loops and weapon priority are solvable.
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.
