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 3D platformer whose joy lives in tight movement and capture-driven traversal.

Execution · Pure Mechanics
Futuristic sequel to the Trials physics-bike series with FMX tricks and brutally precise tracks.
Super Mario Odyssey leans Execution (Pure Mechanics); Trials Fusion leans Execution (Pure Mechanics).
Trials Fusion leans a little harder on execution, though the gap is small.
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Trials Fusion
Frame-tight balance and throttle inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
No adaptive opponents whatsoever.
Trials Fusion
No adaptive opposition
Super Mario Odyssey leans a little harder on variance, though the gap is small.
Super Mario Odyssey
Almost no randomness in level design.
Trials Fusion
Deterministic physics, known tracks
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
Moon routes and movement tech learnable.
Trials Fusion
Optimal lines and trick scoring are 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.
