head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Pure Mechanics
Arcade driving that tests cornering execution over a small set of memorisable tracks.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Need for Speed II 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.
Need for Speed II
Cornering and throttle control decide every race
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Need for Speed II leans a little harder on reads, though the gap is small.
Need for Speed II
AI racers follow rubber-banded scripts, not minds
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.
Need for Speed II
Tracks are fixed; nothing meaningful is hidden
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Need for Speed II
Learning six tracks' racing lines and car choice
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.
