BlurSplit/Second
Axis by axis
Execution7 vs 8
Split/Second leans harder on execution: Drafting, drifting and dodging collapsing set pieces.
Reads3 vs 2
Blur leans harder on reads: Human racers bait and time power-ups against you
Variance4 vs 4
Even - both lean on variance about the same.
Optimization4 vs 4
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.
