Building comparison
head to head
FactoriovsOxygen Not Included
Oxygen Not Included asks more than Factorio, and the gap is variance.
Factorio
Optimization · Pure Optimization
A factory-engineering sandbox about scaling throughput against your own bottlenecks.
Oxygen Not Included
Optimization · Pure Optimization
Engineering precise gas, liquid, and power circuits to keep a subterranean colony alive indefinitely.
Factorio leans Optimization (Pure Optimization); Oxygen Not Included leans Optimization (Pure Optimization).
FactorioOxygen Not Included
Axis by axis
Execution2 vs 1
Factorio leans a little harder on execution, though the gap is small.
Factorio
Some APM in early hand-crafting; otherwise irrelevant.
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.
Factorio
Biters follow fixed pollution rules; no adaptive opponent.
Oxygen Not Included
No adversary of any kind exists in the colony
Variance1 vs 5
Oxygen Not Included leans clearly harder on variance.
Factorio
Resource patch placement adds minor map randomness.
Oxygen Not Included
Asteroid seed and geyser placement carry meaningful but bounded randomness
Optimization10 vs 10
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Factorio
Throughput, ratios, and logistics are the entire game.
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.
