Axis by axis
Execution8 vs 7
F-Zero X leans harder on execution: Sixty-frame control of thirty machines at top speed
Reads1 vs 2
Grid 2 leans harder on reads: Online wheel-to-wheel adds light positional prediction
Variance1 vs 1
Even - both lean on variance about the same.
Optimization5 vs 5
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.
