head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Pure Mechanics
Course-corrected revision restoring difficulty to the trilogy's weakest entry.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Ninja Gaiden 3: Razor's Edge 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.
Ninja Gaiden 3: Razor's Edge
Steel-on-bone counters still demand sharp hands
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Ninja Gaiden 3: Razor's Edge leans a little harder on reads, though the gap is small.
Ninja Gaiden 3: Razor's Edge
Scripted enemy waves
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.
Ninja Gaiden 3: Razor's Edge
Deterministic encounters
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.
Ninja Gaiden 3: Razor's Edge
Simplified systems leave less to solve
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.
