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
A zombie survival sim where long-term planning outweighs moment-to-moment skill.
Mini Metro leans Optimization (Pure Optimization); Project Zomboid leans Optimization (Pure Optimization).
Project Zomboid leans a little harder on execution, though the gap is small.
Mini Metro
light real-time line-drawing
Project Zomboid
Combat is deliberate; precision matters but is slow.
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
Project Zomboid
Zombies follow scripted behaviour; no adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mini Metro
station spawn pattern
Project Zomboid
Loot spawns and zombie distributions randomized.
Mini Metro leans a little harder on optimization, though the gap is small.
Mini Metro
line topology and routing
Project Zomboid
Skill grinding, base setup, and routing define survival.
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.
