head to head
Blades of Steel asks more than Super Mario World, and the gap is reads.

Execution · Pure Mechanics
Arcade hockey reflexes with light shot-angle guessing against human opponents.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Blades of Steel 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.
Blades of Steel
Skating, passing and shot timing decide every rush
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Blades of Steel leans clearly harder on reads.
Blades of Steel
Versus a human, goalie duels become guessing games
Super Mario World
Scripted Koopas adapt to nothing
Blades of Steel leans a little harder on variance, though the gap is small.
Blades of Steel
Fights and bounces add small arcade chaos
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.
Blades of Steel
Angle exploits on the goalie are quickly mapped
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.
