head to head
Neither is simply harder - they are hard in different places. DOOM (2016) demands more optimization; Rescue Mission demands more variance.

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

Execution · Pure Mechanics
A light-gun shooter testing aim while protecting a moving medic.
DOOM (2016) leans Execution (Pure Mechanics); Rescue Mission 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.
Rescue Mission
Light-gun aiming accuracy is the entire game
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.
Rescue Mission
Enemy soldiers spawn on scripts, not adaptively
Rescue Mission leans clearly harder on variance.
DOOM (2016)
Minimal encounter randomness.
Rescue Mission
Enemy appearance timing adds some unpredictability
DOOM (2016) leans clearly harder on optimization.
DOOM (2016)
Rune and weapon mod picks meaningful.
Rescue Mission
Prioritizing threats offers light tactics
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.
