head to head
Unreal Tournament III asks more than Super Mario Odyssey, and the gap is reads.

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

Execution · Pure Mechanics
High-speed arena shooter with twitch duels and warfare-scale vehicle modes.
Super Mario Odyssey leans Execution (Pure Mechanics); Unreal Tournament III leans Execution (Pure Mechanics).
Unreal Tournament III leans a little harder on execution, though the gap is small.
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Unreal Tournament III
Hitscan precision, dodge timing, and vehicle handling rule fights
Unreal Tournament III leans clearly harder on reads.
Super Mario Odyssey
No adaptive opponents whatsoever.
Unreal Tournament III
Human opponents vary routes and dueling habits
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
Almost no randomness in level design.
Unreal Tournament III
Open arenas with fully visible pickups and players
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
Moon routes and movement tech learnable.
Unreal Tournament III
Weapon spawns and power-up timing reward map study
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.
