Axis by axis
Execution6 vs 6
Even - both lean on execution about the same.
Reads2 vs 2
Even - both lean on reads about the same.
Variance1 vs 2
Wii Sports leans harder on variance: Minor physics wobble and CPU behaviour randomness
Optimization2 vs 3
Wii Sports leans harder on optimization: Simple technique tricks like bowling spin are 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.
