Building comparison
head to head
Mini MetrovsOxygen Not Included
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Mini Metro
Optimization · Pure Optimization
Minimalist transit puzzle; route topology under spawning pressure.
Oxygen Not Included
Optimization · Pure Optimization
Engineering precise gas, liquid, and power circuits to keep a subterranean colony alive indefinitely.
Mini Metro leans Optimization (Pure Optimization); Oxygen Not Included leans Optimization (Pure Optimization).

Axis by axis
Execution2 vs 1
Mini Metro leans a little harder on execution, though the gap is small.
Mini Metro
light real-time line-drawing
Oxygen Not Included
All inputs are build-order clicks; no twitch required
Reads0 vs 0
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
Oxygen Not Included
No adversary of any kind exists in the colony
Variance5 vs 5
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
Oxygen Not Included
Asteroid seed and geyser placement carry meaningful but bounded randomness
Optimization9 vs 10
Oxygen Not Included leans a little harder on optimization, though the gap is small.
Mini Metro
line topology and routing
Oxygen Not Included
Gas, liquid, and power engineering are essentially a solvable engineering puzzle
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.
