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
Dodging scripted bullet waves while grinding an upgrade economy to brute-force medals.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Sky Force Anniversary 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.
Sky Force Anniversary
Weaving dense bullet patterns is the entire moment-to-moment test
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.
Sky Force Anniversary
Enemy waves follow fixed scripts every run
Super Mario Odyssey
No adaptive opponents whatsoever.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sky Force Anniversary
Spawns are deterministic; almost nothing to map
Super Mario Odyssey
Almost no randomness in level design.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Sky Force Anniversary
Upgrade grinding and medal-route planning shape progression
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.
