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 bullet-hell shmup testing dodging precision and scoring optimisation against fixed patterns.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
eXceed Gun Bullet Children leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
eXceed Gun Bullet Children leans a little harder on execution, though the gap is small.
eXceed Gun Bullet Children
Weaving through dense bullet patterns is the whole test
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.
eXceed Gun Bullet Children
Solo bullet hell, no adaptive opponent
Super Mario Odyssey
No adaptive opponents whatsoever.
eXceed Gun Bullet Children leans a little harder on variance, though the gap is small.
eXceed Gun Bullet Children
Patterns are fixed and memorisable, not random
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.
eXceed Gun Bullet Children
Scoring systems and weapon choice reward optimisation
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.
