head to head
Neither is simply harder - they are hard in different places. Robot Unicorn Attack demands more variance; Super Mario Odyssey demands more optimization.

Execution · Pure Mechanics
An endless runner testing reactive jump and dash timing for distance.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Robot Unicorn Attack leans Execution (Pure Mechanics); Super Mario Odyssey 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.
Robot Unicorn Attack
Precise jump and dash timing decides every run
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Robot Unicorn Attack
Solo endless runner, no opponent
Super Mario Odyssey
No adaptive opponents whatsoever.
Robot Unicorn Attack leans clearly harder on variance.
Robot Unicorn Attack
Procedural obstacle generation adds reaction demand
Super Mario Odyssey
Almost no randomness in level design.
Super Mario Odyssey leans clearly harder on optimization.
Robot Unicorn Attack
Limited strategy beyond reactive timing
Super Mario Odyssey
Moon routes and movement tech learnable.
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.
