head to head
TimeSplitters 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
A fast arcade FPS whose skill test is twitch aim plus couch-rival prediction.
Super Mario World leans Execution (Pure Mechanics); TimeSplitters 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.
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
TimeSplitters
Fast arcade gunplay rewards twitch aim
TimeSplitters leans clearly harder on reads.
Super Mario World
Scripted Koopas adapt to nothing
TimeSplitters
Local multiplayer adds human guessing; bots do not adapt
TimeSplitters leans a little harder on variance, though the gap is small.
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
TimeSplitters
Spawn and pickup timing add mild uncertainty
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario World
Secret exits and route knowledge add a modest solvable layer
TimeSplitters
Challenge times and map control 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.
