head to head
Super Mario World asks more than Duck Hunt, and the gap is optimization.

Execution · Pure Mechanics
The NES light-gun classic of shooting ducks and enduring the dog.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Duck Hunt 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.
Duck Hunt
Pure light-gun aim and reaction speed
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.
Duck Hunt
Ducks fly on simple patterns
Super Mario World
Scripted Koopas adapt to nothing
Duck Hunt leans a little harder on variance, though the gap is small.
Duck Hunt
Flight paths vary a little
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Super Mario World leans clearly harder on optimization.
Duck Hunt
Almost nothing to optimise beyond aim
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.
