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.

Optimization · Pure Optimization
Minimalist transit puzzle; route topology under spawning pressure.

Optimization · Pure Optimization
An auto-attacker where picking the right weapon evolutions wins by itself.
Mini Metro leans Optimization (Pure Optimization); Vampire Survivors leans Optimization (Pure Optimization).
Mini Metro leans a little harder on execution, though the gap is small.
Mini Metro
light real-time line-drawing
Vampire Survivors
Movement is trivial; no aim or precision required.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mini Metro
no adversary
Vampire Survivors
Enemies follow fixed spawn scripts; no adaptive opponent.
Mini Metro leans a little harder on variance, though the gap is small.
Mini Metro
station spawn pattern
Vampire Survivors
Level-up offerings and pickup drops are randomized.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mini Metro
line topology and routing
Vampire Survivors
Evolution paths and weapon combinations fully solve the run.
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.
