Building comparison
head to head
FactoriovsSatisfactory
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Factorio
Optimization · Pure Optimization
A factory-engineering sandbox about scaling throughput against your own bottlenecks.
Satisfactory
Optimization · Pure Optimization
A first-person factory builder that is pure logistics optimization.
Factorio leans Optimization (Pure Optimization); Satisfactory leans Optimization (Pure Optimization).

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.
Satisfactory
Light platforming, no real mechanical ceiling.
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.
Satisfactory
No adaptive opponent in the world.
Variance1 vs 1
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Factorio
Resource patch placement adds minor map randomness.
Satisfactory
Resource nodes are fixed once mapped.
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.
Satisfactory
Ratios, logistics, and factory layout are everything.
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.
