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

Execution · Pure Mechanics
A fast reflex platformer about swinging through hazardous environments precisely.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Alien Spidy 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.
Alien Spidy
Quick swinging and precise reflexes define every level
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.
Alien Spidy
Solo platformer with no adaptive opponent
Super Mario Odyssey
No adaptive opponents whatsoever.
Alien Spidy leans a little harder on variance, though the gap is small.
Alien Spidy
Hazards are fixed and learnable
Super Mario Odyssey
Almost no randomness in level design.
Super Mario Odyssey leans a little harder on optimization, though the gap is small.
Alien Spidy
Optimal pathing speeds collection runs
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.
