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 arcade shmup testing dodging reflexes against memorised enemy waves.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Mega Force leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Mega Force leans a little harder on execution, though the gap is small.
Mega Force
Perfect dodging and shooting would clear every wave alone
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.
Mega Force
Enemy waves are scripted, nothing adapts
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.
Mega Force
Spawn patterns repeat identically and map quickly
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Mega Force leans a little harder on optimization, though the gap is small.
Mega Force
Memorising wave order and scoring spots maximises runs
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.
