head to head
Half-Life: AlyxvsSuper Mario World
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.
Half-Life: Alyx
Execution · Pure Mechanics
VR Half-Life where hand-presence interaction defines every fight.
Super Mario World
Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Half-Life: Alyx leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Half-Life: AlyxSuper Mario World
Axis by axis
Execution7 vs 7
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life: Alyx
VR aim, reload, and grab inputs intense.
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Reads1 vs 0
Half-Life: Alyx leans a little harder on reads, though the gap is small.
Half-Life: Alyx
Combine and headcrabs scripted.
Super Mario World
Scripted Koopas adapt to nothing
Variance2 vs 1
Half-Life: Alyx leans a little harder on variance, though the gap is small.
Half-Life: Alyx
Resource and encounter variance light.
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Optimization3 vs 4
Super Mario World leans a little harder on optimization, though the gap is small.
Half-Life: Alyx
Few systems to tune.
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.
