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

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

Execution · Pure Mechanics
Arcade dogfighter about staying airborne amid swarming bullets on pure stick skill.
DOOM (2016) leans Execution (Pure Mechanics); Luftrausers 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.
Luftrausers
Momentum-based dogfighting demands constant precise control
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Luftrausers
Enemy planes follow simple fixed behaviors
Luftrausers leans a little harder on variance, though the gap is small.
DOOM (2016)
Minimal encounter randomness.
Luftrausers
Spawn patterns vary slightly
DOOM (2016) leans clearly harder on optimization.
DOOM (2016)
Rune and weapon mod picks meaningful.
Luftrausers
Part combos tweak the score game
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.
