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

Execution · Pure Mechanics
A 2D brawler testing counter timing and combo execution against scripted waves.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Shank 2 leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
Super Mario Odyssey leans a little harder on execution, though the gap is small.
Shank 2
Combo juggling, counters and dodge timing carry every brawl
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Shank 2 leans a little harder on reads, though the gap is small.
Shank 2
Enemies telegraph fixed attacks; survival co-op stays scripted
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.
Shank 2
Encounters are deterministic set pieces
Super Mario Odyssey
Almost no randomness in level design.
Super Mario Odyssey leans a little harder on optimization, though the gap is small.
Shank 2
Weapon synergies and crowd-priority knowledge add depth
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.
