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 vertical bullet-hell shmup testing precise dodging through dense scripted patterns.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
eXceed 2nd: Vampire REX leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
eXceed 2nd: Vampire REX leans a little harder on execution, though the gap is small.
eXceed 2nd: Vampire REX
Dodging dense bullet patterns at speed is the entire 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 2nd: Vampire REX
Solo - enemies fire fixed scripted patterns, no adaptation
Super Mario Odyssey
No adaptive opponents whatsoever.
eXceed 2nd: Vampire REX leans a little harder on variance, though the gap is small.
eXceed 2nd: Vampire REX
Patterns are deterministic and memorisable, 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.
eXceed 2nd: Vampire REX
Polarity routing and scoring systems reward learned play
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.
