Axis by axis
Execution2 vs 1
Factorio leans harder on execution: Some APM in early hand-crafting; otherwise irrelevant.
Reads0 vs 0
Even - both lean on reads about the same.
Variance1 vs 2
Stationeers leans harder on variance: Planet conditions known, failures come from your systems
Optimization10 vs 10
Even - both lean on optimization about the same.
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
