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
Spectacle hack-and-slash where reflexes and combo flow drive every fight.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
God of War III 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.
God of War III
Combo execution and QTE timing carry combat.
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
God of War III leans a little harder on reads, though the gap is small.
God of War III
Bosses fully scripted spectacle.
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.
God of War III
Almost no randomness.
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.
God of War III
Upgrade paths short and obvious.
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.
