head to head
Neither is simply harder - they are hard in different places. Osu! Tatakae! Ouendan demands more execution; Super Mario World demands more optimization.

Execution · Pure Mechanics
DS stylus rhythm game where a male cheer squad saves lives through perfectly timed taps.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Osu! Tatakae! Ouendan leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Osu! Tatakae! Ouendan leans clearly harder on execution.
Osu! Tatakae! Ouendan
Stylus tap, drag, and spin precision at high tempo
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.
Osu! Tatakae! Ouendan
Charts never adapt
Super Mario World
Scripted Koopas adapt to nothing
Super Mario World leans a little harder on variance, though the gap is small.
Osu! Tatakae! Ouendan
Fully fixed note placements
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Super Mario World leans clearly harder on optimization.
Osu! Tatakae! Ouendan
Memorizing layouts matters less than stylus accuracy
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.
