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 1
Even - both lean on variance about the same.
Optimization10 vs 9
Factorio leans harder on optimization: Throughput, ratios, and logistics are the entire game.
