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 3D platformer whose joy lives in tight movement and capture-driven traversal.

Execution · Pure Mechanics
Tests twin-stick reflexes and threat triage under relentless arcade pressure.
Super Mario Odyssey leans Execution (Pure Mechanics); Super Stardust Ultra leans Execution (Pure Mechanics).
Super Stardust Ultra leans a little harder on execution, though the gap is small.
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Super Stardust Ultra
Twin-stick dodging through dense asteroid fields is everything
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.
Super Stardust Ultra
Waves are spawned patterns, not adaptive opponents
Super Stardust Ultra leans a little harder on variance, though the gap is small.
Super Mario Odyssey
Almost no randomness in level design.
Super Stardust Ultra
Spawn timing varies slightly but is quickly familiar
Super Mario Odyssey leans a little harder on optimization, though the gap is small.
Super Mario Odyssey
Moon routes and movement tech learnable.
Super Stardust Ultra
Weapon choice and multiplier management refine scores
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.
