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
Grinding deterministic tracks for the perfect line and the flawless run.
Super Mario Odyssey leans Execution (Pure Mechanics); TrackMania 2: Stadium leans Execution (Pure Mechanics).
TrackMania 2: Stadium leans a little harder on execution, though the gap is small.
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
TrackMania 2: Stadium
Perfect inputs ARE the game - hundredths decide leaderboards
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.
TrackMania 2: Stadium
Ghost racing - opponents never interact with your run
Super Mario Odyssey leans a little harder on variance, though the gap is small.
Super Mario Odyssey
Almost no randomness in level design.
TrackMania 2: Stadium
Fully deterministic physics, identical track every attempt
TrackMania 2: Stadium leans a little harder on optimization, though the gap is small.
Super Mario Odyssey
Moon routes and movement tech learnable.
TrackMania 2: Stadium
Finding the optimal racing line is half the hunt
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.
