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

Execution · Pure Mechanics
Pure aim and movement skill tested against adaptive human opponents competing for spawn-cycle dominance.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Quake III Arena leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
Quake III Arena leans a little harder on execution, though the gap is small.
Quake III Arena
Rail and rocket aim at speed is the entire game
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Quake III Arena leans clearly harder on reads.
Quake III Arena
Human opponents adapt their routes and timings in direct response
Super Mario Odyssey
No adaptive opponents whatsoever.
Quake III Arena leans a little harder on variance, though the gap is small.
Quake III Arena
Spawn locations have mild randomness but are quickly mapped
Super Mario Odyssey
Almost no randomness in level design.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Quake III Arena
Armor and weapon timing routes are learnable and highly leveraged
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.
