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
A rail shooter testing aim and reflexes through scripted space battles.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Star Wars Arcade 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.
Star Wars Arcade
Aiming and dodging in rail combat decides survival
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Star Wars Arcade leans a little harder on reads, though the gap is small.
Star Wars Arcade
Enemy ships follow scripted attack patterns
Super Mario World
Scripted Koopas adapt to nothing
Star Wars Arcade leans a little harder on variance, though the gap is small.
Star Wars Arcade
Minor variation in enemy approaches
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.
Star Wars Arcade
Memorizing waves and conserving shields helps
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.
