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

Execution · Pure Mechanics
A test of fast, precise shooting and map navigation against scripted but relentless enemies.

Execution · Pure Mechanics
A bullet-grazing shmup testing precise dodging and scoring routes.
Doom (1993) leans Execution (Pure Mechanics); Psyvariar 3 leans Execution (Pure Mechanics).
Psyvariar 3 leans a little harder on execution, though the gap is small.
Doom (1993)
Precise movement and shooting against relentless enemy pressure
Psyvariar 3
Grazing bullets at the edge of death is pure twitch
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Doom (1993)
Enemies follow scripted patrol and attack patterns, not adaptive
Psyvariar 3
Scripted bullet patterns, no adaptive opponent
Doom (1993) leans a little harder on variance, though the gap is small.
Doom (1993)
Enemy placement is fixed but unknown on first run through levels
Psyvariar 3
Fixed patterns, memorizable once learned
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Doom (1993)
Level routing and resource management determine survival efficiency
Psyvariar 3
Buzz-system scoring routes reward optimized play
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.
