head to head
DOOM (2016) asks more than Red Steel, and the gap is execution.

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

Execution · Pure Mechanics
Wrestling motion-control aim and swordplay through fixed scripted shootouts.
DOOM (2016) leans Execution (Pure Mechanics); Red Steel leans Execution (Pure Mechanics).
DOOM (2016) leans clearly harder on execution.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
Red Steel
Wiimote aiming and sword swings are the whole physical test
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Red Steel
Enemies are scripted spawns, never 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.
Red Steel
Encounters are fixed once seen
DOOM (2016) leans clearly harder on optimization.
DOOM (2016)
Rune and weapon mod picks meaningful.
Red Steel
Light level memorisation and weapon choices
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.
