head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

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

Execution · Pure Mechanics
A remixed arcade shooter testing reflex precision and learned scoring-chain systems.
DOOM (2016) leans Execution (Pure Mechanics); Space Invaders Extreme 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.
Space Invaders Extreme
Rhythm-paced dodging and precise shots at high speed
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Space Invaders Extreme
Invader formations are scripted patterns
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.
Space Invaders Extreme
Power-up rounds vary slightly between runs
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Rune and weapon mod picks meaningful.
Space Invaders Extreme
Chaining flicker patterns and fever modes is deep score tech
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.
