Axis by axis
Execution7 vs 7
Even - both lean on execution about the same.
Reads2 vs 2
Even - both lean on reads about the same.
Variance1 vs 2
Ridge Racer Unbounded leans harder on variance: Destruction chaos adds modest track noise
Optimization5 vs 4
Grid 2 leans harder on optimization: Racing lines, braking points and car selection are studyable
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
