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
The side-scrolling shmup now immortal for its 'all your base' intro.
DOOM (2016) leans Execution (Pure Mechanics); Zero Wing 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.
Zero Wing
Bullet weaving and tractor-beam captures under fire
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Zero Wing
Enemy waves fully scripted
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.
Zero Wing
Deterministic patterns every run
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.
Zero Wing
Memorising wave layouts and power-up routes
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.
