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 top-down shmup testing dodging and aiming against memorizable bullet patterns.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Alltynex Second leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
Alltynex Second leans a little harder on execution, though the gap is small.
Alltynex Second
Bullet-hell dodging and aiming are the whole skill
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Alltynex Second leans a little harder on reads, though the gap is small.
Alltynex Second
Bosses are fixed patterns, not adaptive
Super Mario Odyssey
No adaptive opponents whatsoever.
Alltynex Second leans a little harder on variance, though the gap is small.
Alltynex Second
Patterns memorizable, little true randomness
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.
Alltynex Second
Learning safe routes and sword timing optimizes survival
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.
