head to head
Ninja Gaiden Sigma 2 asks more than Super Mario World, and the gap is execution.

Execution · Pure Mechanics
Faster, gorier sequel built around dismembering aggressive enemies before they swarm you.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Ninja Gaiden Sigma 2 leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Ninja Gaiden Sigma 2 leans clearly harder on execution.
Ninja Gaiden Sigma 2
Delimb-and-finish combat under constant projectile pressure stays brutal
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.
Ninja Gaiden Sigma 2
Aggressive enemy AI remains pattern-driven
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.
Ninja Gaiden Sigma 2
Fixed missions; little randomness across runs
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Ninja Gaiden Sigma 2 leans clearly harder on optimization.
Ninja Gaiden Sigma 2
Weapon matchups and essence routing reward system study
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.
