head to head
Neither is simply harder - they are hard in different places. Arkanoid: Doh It Again demands more variance; Super Mario Odyssey demands more optimization.

Execution · Pure Mechanics
A reflex test of paddle precision against accelerating ball physics.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Arkanoid: Doh It Again 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.
Arkanoid: Doh It Again
Paddle precision under accelerating ball speed is everything
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.
Arkanoid: Doh It Again
No opponent - bricks do not adapt
Super Mario Odyssey
No adaptive opponents whatsoever.
Arkanoid: Doh It Again leans clearly harder on variance.
Arkanoid: Doh It Again
Power-up drops and ball angles add bounded randomness
Super Mario Odyssey
Almost no randomness in level design.
Super Mario Odyssey leans clearly harder on optimization.
Arkanoid: Doh It Again
Brick-clearing order and power-up choices have known answers
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.
