head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
A classic arcade run-and-gun shooter with dodge-roll-based combat.

Execution · Pure Mechanics
VR Half-Life where hand-presence interaction defines every fight.
Cabal leans Execution (Pure Mechanics); Half-Life: Alyx leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Cabal
precise dodge-rolling and aiming execution
Half-Life: Alyx
VR aim, reload, and grab inputs intense.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cabal
enemies scripted, no real adaptation
Half-Life: Alyx
Combine and headcrabs scripted.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cabal
enemy spawn randomness is modest
Half-Life: Alyx
Resource and encounter variance light.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cabal
limited strategy beyond memorizing waves
Half-Life: Alyx
Few systems to tune.
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.
