head to head
Quake III Arena asks more than Super Mario World, 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
Precise jump execution across fixed levels with secrets to memorise.
Quake III Arena leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Quake III Arena leans clearly harder on execution.
Quake III Arena
Rail and rocket aim at speed is the entire game
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Quake III Arena leans clearly harder on reads.
Quake III Arena
Human opponents adapt their routes and timings in direct response
Super Mario World
Scripted Koopas adapt to nothing
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 World
Levels are fixed; nothing hidden survives one playthrough
Quake III Arena leans a little harder on optimization, though the gap is small.
Quake III Arena
Armor and weapon timing routes are learnable and highly leveraged
Super Mario World
Secret exits and route knowledge add a modest solvable layer
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.
