head to head
Rocket League asks more than Super Mario World, and the gap is reads.

Execution · Pure Mechanics
Mechanical car-soccer where execution is the ceiling.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Rocket League leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Rocket League leans clearly harder on execution.
Rocket League
Aerials, flicks, dribbles, pure mechanical ceiling
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Rocket League leans clearly harder on reads.
Rocket League
Rotations and 50-50 reads against humans
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.
Rocket League
Almost deterministic physics
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Super Mario World leans a little harder on optimization, though the gap is small.
Rocket League
Training routines, rotation theory
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.
