head to head
Arkanoid: Doh It Again asks more than Super Mario World, and the gap is variance.

Execution · Pure Mechanics
A reflex test of paddle precision against accelerating ball physics.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Arkanoid: Doh It Again 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.
Arkanoid: Doh It Again
Paddle precision under accelerating ball speed is everything
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.
Arkanoid: Doh It Again
No opponent - bricks do not adapt
Super Mario World
Scripted Koopas adapt to nothing
Arkanoid: Doh It Again leans clearly harder on variance.
Arkanoid: Doh It Again
Power-up drops and ball angles add bounded randomness
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.
Arkanoid: Doh It Again
Brick-clearing order and power-up choices have known answers
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.
