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

Execution · Pure Mechanics
A classic Contra-style run-and-gun about precise reflexes and firepower.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Operation C leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Operation C leans a little harder on execution, though the gap is small.
Operation C
precise run-and-gun reflexes and dodging
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.
Operation C
scripted enemy patterns, no adaptation
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.
Operation C
minimal randomness
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.
Operation C
weapon pickup routing knowledge
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.
