head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.

Execution · Pure Mechanics
The side-scrolling shmup now immortal for its 'all your base' intro.
Super Mario Odyssey leans Execution (Pure Mechanics); Zero Wing 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.
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Zero Wing
Bullet weaving and tractor-beam captures under fire
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
No adaptive opponents whatsoever.
Zero Wing
Enemy waves fully scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
Almost no randomness in level design.
Zero Wing
Deterministic patterns every run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
Moon routes and movement tech learnable.
Zero Wing
Memorising wave layouts and power-up routes
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.
