head to head
Tetris: Axis asks more than Super Mario World, and the gap is variance.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.

Execution · Pure Mechanics
A portable Tetris entry with varied modes atop the classic falling-block formula.
Super Mario World leans Execution (Pure Mechanics); Tetris: Axis leans Execution (Pure Mechanics).
Tetris: Axis leans a little harder on execution, though the gap is small.
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Tetris: Axis
fast precise piece placement and rotation
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario World
Scripted Koopas adapt to nothing
Tetris: Axis
no opponent modeling in main mode
Tetris: Axis leans clearly harder on variance.
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Tetris: Axis
random piece sequence drives play
Tetris: Axis leans a little harder on optimization, though the gap is small.
Super Mario World
Secret exits and route knowledge add a modest solvable layer
Tetris: Axis
stacking strategy and clear efficiency
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.
