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 top-down war shooter testing dodging and aim through scripted enemy waves.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Iron Tank: The Invasion of Normandy 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.
Iron Tank: The Invasion of Normandy
Dodging fire and aiming under the scrolling assault is constant
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Iron Tank: The Invasion of Normandy leans a little harder on reads, though the gap is small.
Iron Tank: The Invasion of Normandy
Enemies spawn on fixed scripts, no adaptation
Super Mario Odyssey
No adaptive opponents whatsoever.
Iron Tank: The Invasion of Normandy leans a little harder on variance, though the gap is small.
Iron Tank: The Invasion of Normandy
Some enemy placement surprises but levels are fixed
Super Mario Odyssey
Almost no randomness in level design.
Super Mario Odyssey leans a little harder on optimization, though the gap is small.
Iron Tank: The Invasion of Normandy
Weapon powerup management and routing help survival
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.
