head to head
Galaga '88 asks more than Super Mario World, and the gap is variance.

Execution · Pure Mechanics
Namco's lavish Galaga sequel adds dimension warps and ship-stacking to classic formation shooting.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Galaga '88 leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Galaga '88 leans a little harder on execution, though the gap is small.
Galaga '88
Precise dodging and shooting through dense dive patterns.
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.
Galaga '88
Aliens attack on choreographed scripts.
Super Mario World
Scripted Koopas adapt to nothing
Galaga '88 leans clearly harder on variance.
Galaga '88
Dive timing and dimension-warp triggers vary.
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Galaga '88 leans a little harder on optimization, though the gap is small.
Galaga '88
Triple-ship management and warp routing reward planning.
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.
