head to head
Race the Sun asks more than Super Mario World, and the gap is variance.

Execution · Pure Mechanics
Pure reflex weaving through procedurally shuffled obstacle fields before sundown.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Race the Sun leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Race the Sun leans a little harder on execution, though the gap is small.
Race the Sun
Split-second weaving at ever-rising speed is the whole test
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Race the Sun
Obstacles never predict you
Super Mario World
Scripted Koopas adapt to nothing
Race the Sun leans clearly harder on variance.
Race the Sun
Procedural daily worlds keep layouts unknown
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.
Race the Sun
Powerup priorities and scoring lines are quickly learned
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.
