Building comparison
head to head
FactoriovsKerbal Space Program
Kerbal Space Program asks more than Factorio, and the gap is execution.
Factorio
Optimization · Pure Optimization
A factory-engineering sandbox about scaling throughput against your own bottlenecks.
Kerbal Space Program
Optimization · Pure Optimization
Rocket engineering sandbox about orbital mechanics.
Factorio leans Optimization (Pure Optimization); Kerbal Space Program leans Optimization (Pure Optimization).
FactorioKerbal Space Program
Axis by axis
Execution2 vs 5
Kerbal Space Program leans clearly harder on execution.
Factorio
Some APM in early hand-crafting; otherwise irrelevant.
Kerbal Space Program
Manual piloting, docking precision
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.
Kerbal Space Program
No adaptive opponents
Variance1 vs 2
Kerbal Space Program leans a little harder on variance, though the gap is small.
Factorio
Resource patch placement adds minor map randomness.
Kerbal Space Program
Light reentry and physics variance
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.
Kerbal Space Program
Rocket design, delta-v budget, mission planning
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.
