head to head
DOOM (2016) asks more than Bit.Trip Presents... Runner2: Future Legend of Rhythm Alien, and the gap is optimization.

Execution · Pure Mechanics
Frame-precise rhythm-platforming execution on fully deterministic tracks.

Execution · Pure Mechanics
Push-forward arena FPS where movement and aim are the whole game.
Bit.Trip Presents... Runner2: Future Legend of Rhythm Alien leans Execution (Pure Mechanics); DOOM (2016) 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.
Bit.Trip Presents... Runner2: Future Legend of Rhythm Alien
Frame-tight rhythm inputs on fixed tracks are everything
DOOM (2016)
Aim, movement, glory-kill timing all peak.
DOOM (2016) leans a little harder on reads, though the gap is small.
Bit.Trip Presents... Runner2: Future Legend of Rhythm Alien
No opponent; the track never adapts
DOOM (2016)
Demons scripted attack patterns.
DOOM (2016) leans a little harder on variance, though the gap is small.
Bit.Trip Presents... Runner2: Future Legend of Rhythm Alien
Levels are fully deterministic
DOOM (2016)
Minimal encounter randomness.
DOOM (2016) leans clearly harder on optimization.
Bit.Trip Presents... Runner2: Future Legend of Rhythm Alien
Memorising layouts helps but execution still gates clears
DOOM (2016)
Rune and weapon mod picks meaningful.
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.
