Axis by axis
Execution9 vs 9
Even - both lean on execution about the same.
Reads1 vs 0
Inertial Drift leans harder on reads: Primarily single-player time-attack; minimal opponent interaction
Variance1 vs 0
Inertial Drift leans harder on variance: Deterministic tracks with no hidden randomness
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.
