head to head
Unreal Tournament (1999) asks more than Super Mario World, and the gap is reads.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.

Execution · Pure Mechanics
High-speed aim and movement dominance against human opponents fighting for weapon and map control.
Super Mario World leans Execution (Pure Mechanics); Unreal Tournament (1999) leans Execution (Pure Mechanics).
Unreal Tournament (1999) leans clearly harder on execution.
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Unreal Tournament (1999)
Shock combo and flak cannon timing demand peak motor precision
Unreal Tournament (1999) leans clearly harder on reads.
Super Mario World
Scripted Koopas adapt to nothing
Unreal Tournament (1999)
Human opponents continuously adapt routes and engagement choices
Unreal Tournament (1999) leans a little harder on variance, though the gap is small.
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Unreal Tournament (1999)
Map spawns are minor; most information is visible or predictable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario World
Secret exits and route knowledge add a modest solvable layer
Unreal Tournament (1999)
Weapon prioritisation and map control are learnable but secondary
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.
