Grid 2Rocket League
Axis by axis
Execution7 vs 10
Rocket League leans harder on execution: Aerials, flicks, dribbles, pure mechanical ceiling
Reads2 vs 6
Rocket League leans harder on reads: Rotations and 50-50 reads against humans
Variance1 vs 1
Even - both lean on variance about the same.
Optimization5 vs 3
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.
