head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Pure Mechanics
A cover-based run-and-gun testing precise shooting and pattern memorization.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Rolling Thunder 2 leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Rolling Thunder 2
Precise shooting, cover-jumping and timing carry every stage
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Rolling Thunder 2 leans a little harder on reads, though the gap is small.
Rolling Thunder 2
Solo/co-op - enemies follow scripted spawn patterns
Super Mario Odyssey
No adaptive opponents whatsoever.
Rolling Thunder 2 leans a little harder on variance, though the gap is small.
Rolling Thunder 2
Enemy appearances are fixed once memorized
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.
Rolling Thunder 2
Learning spawn points and weapon management is the meta-game
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.
