head to head
Lethal Enforcers II: Gun Fighters asks more than Duck Hunt, and the gap is execution.

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

Execution · Pure Mechanics
A light-gun shooter testing raw aiming speed against pop-up targets.
Duck Hunt leans Execution (Pure Mechanics); Lethal Enforcers II: Gun Fighters leans Execution (Pure Mechanics).
Lethal Enforcers II: Gun Fighters leans clearly harder on execution.
Duck Hunt
Pure light-gun aim and reaction speed
Lethal Enforcers II: Gun Fighters
Light-gun aiming speed and accuracy are the whole game
Lethal Enforcers II: Gun Fighters leans a little harder on reads, though the gap is small.
Duck Hunt
Ducks fly on simple patterns
Lethal Enforcers II: Gun Fighters
Enemies pop in scripted positions, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Duck Hunt
Flight paths vary a little
Lethal Enforcers II: Gun Fighters
Minor pop-up timing variance, mostly fixed sequences
Lethal Enforcers II: Gun Fighters leans a little harder on optimization, though the gap is small.
Duck Hunt
Almost nothing to optimise beyond aim
Lethal Enforcers II: Gun Fighters
Learning shooting-gallery layouts adds modest optimization
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.
