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-grazing shoot-em-up about leveling by skimming enemy fire as closely as possible.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Psyvariar Delta leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
Psyvariar Delta leans a little harder on execution, though the gap is small.
Psyvariar Delta
Grazing bullets at the edge of death defines mastery
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Psyvariar Delta leans a little harder on reads, though the gap is small.
Psyvariar Delta
Enemy fire is scripted, not adaptive
Super Mario Odyssey
No adaptive opponents whatsoever.
Psyvariar Delta leans a little harder on variance, though the gap is small.
Psyvariar Delta
Patterns are fixed and memorizable
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.
Psyvariar Delta
Buzz-chaining routes and leveling strategy reward planning
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.
