head to head
Super Mario World asks more than Kinect Adventures, and the gap is optimization.

Execution · Pure Mechanics
Flailing accurately at motion-tracked minigames, nothing deeper.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Kinect Adventures leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Super Mario World leans clearly harder on execution.
Kinect Adventures
Full-body motion timing is the only test present
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.
Kinect Adventures
No adaptive opposition in minigames
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.
Kinect Adventures
Obstacle sequences barely vary
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Super Mario World leans clearly harder on optimization.
Kinect Adventures
Minigames are too simple to optimise meaningfully
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.
