Axis by axis
Execution8 vs 8
Even - both lean on execution about the same.
Reads0 vs 1
World Circuit: The Grand Prix Race Simulation leans harder on reads: AI drivers follow fixed racing lines, not minds
Variance1 vs 1
Even - both lean on variance about the same.
Optimization7 vs 6
Gran Turismo 4 leans harder on optimization: Event-by-event car and tune selection is deeply solvable
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
