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

Execution · Pure Mechanics
The stylish PS1 arcade racer with a grand prix story and a legendary soundtrack.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
R4: Ridge Racer Type 4 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.
R4: Ridge Racer Type 4
Grip versus drift car control rewards precise corner technique
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.
R4: Ridge Racer Type 4
Rival AI is scripted per race
Super Mario Odyssey
No adaptive opponents whatsoever.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
R4: Ridge Racer Type 4
Fixed tracks; car unlock tree is deterministic
Super Mario Odyssey
Almost no randomness in level design.
Super Mario Odyssey leans a little harder on optimization, though the gap is small.
R4: Ridge Racer Type 4
Choosing machines and mastering lines is light routing
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.
