Axis by axis
Execution9 vs 8
F-Zero GX leans harder on execution: Snaking and frame-tight control at absurd speeds
Reads1 vs 1
Even - both lean on reads about the same.
Variance1 vs 1
Even - both lean on variance about the same.
Optimization5 vs 6
rFactor leans harder on optimization: Setup engineering and fuel strategy are a deep solvable layer
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
