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 precision-platforming metroidvania built around fluid traversal.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Ori and the Blind Forest leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
Super Mario Odyssey leans a little harder on execution, though the gap is small.
Ori and the Blind Forest
Precise platforming and bash-chain escape sequences
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Ori and the Blind Forest leans a little harder on reads, though the gap is small.
Ori and the Blind Forest
Scripted enemies, no adaptive opponent
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.
Ori and the Blind Forest
Fixed layouts, minimal randomness
Super Mario Odyssey
Almost no randomness in level design.
Super Mario Odyssey leans a little harder on optimization, though the gap is small.
Ori and the Blind Forest
Ability routing and shard builds matter
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.
