Axis by axis
Execution9 vs 9
Even - both lean on execution about the same.
Reads0 vs 1
Inertial Drift leans harder on reads: Primarily single-player time-attack; minimal opponent interaction
Variance1 vs 1
Even - both lean on variance about the same.
Optimization6 vs 5
Cuphead leans harder on optimization: Loadouts and boss phase order are fully learnable.
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
