head to head
Tetris Effect: Connected asks more than Super Mario Odyssey, and the gap is variance.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.

Execution · Pure Mechanics
The classic execution-under-acceleration test wrapped in an immersive audiovisual experience.
Super Mario Odyssey leans Execution (Pure Mechanics); Tetris Effect: Connected leans Execution (Pure Mechanics).
Tetris Effect: Connected leans a little harder on execution, though the gap is small.
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Tetris Effect: Connected
Precision placement under acceleration is the entire skill ceiling
Tetris Effect: Connected leans a little harder on reads, though the gap is small.
Super Mario Odyssey
No adaptive opponents whatsoever.
Tetris Effect: Connected
Zone-battle opponents exist but format leans on execution
Tetris Effect: Connected leans clearly harder on variance.
Super Mario Odyssey
Almost no randomness in level design.
Tetris Effect: Connected
Piece bag is bounded random but quickly mappable
Super Mario Odyssey leans a little harder on optimization, though the gap is small.
Super Mario Odyssey
Moon routes and movement tech learnable.
Tetris Effect: Connected
T-spin and stacking strategy is knowable but execution overrides it
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.
