head to head
Neither is simply harder - they are hard in different places. Sports Champions 2 demands more reads; Super Mario World demands more optimization.

Execution · Pure Mechanics
Testing how precisely you can swing a Move controller across six sports.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Sports Champions 2 leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Sports Champions 2
Motion-controlled swings and punches reward physical precision
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Sports Champions 2 leans clearly harder on reads.
Sports Champions 2
Local rivals can be baited in boxing or tennis, lightly
Super Mario World
Scripted Koopas adapt to nothing
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sports Champions 2
Events are deterministic given your motion
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Super Mario World leans clearly harder on optimization.
Sports Champions 2
Technique tips exist but systems stay shallow
Super Mario World
Secret exits and route knowledge add a modest solvable layer
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
