head to head
Wii Sports asks more than Super Mario World, and the gap is reads.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.

Execution · Pure Mechanics
Motion-controlled tennis, bowling, golf, baseball and boxing built around simple swing gestures.
Super Mario World leans Execution (Pure Mechanics); Wii Sports leans Execution (Pure Mechanics).
Super Mario World leans a little harder on execution, though the gap is small.
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Wii Sports
Motion swing timing and accuracy decide every event
Wii Sports leans clearly harder on reads.
Super Mario World
Scripted Koopas adapt to nothing
Wii Sports
Casual local opponents add light mind games
Wii Sports leans a little harder on variance, though the gap is small.
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Wii Sports
Minor physics wobble and CPU behaviour randomness
Super Mario World leans a little harder on optimization, though the gap is small.
Super Mario World
Secret exits and route knowledge add a modest solvable layer
Wii Sports
Simple technique tricks like bowling spin are learnable
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.
