head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Pure Mechanics
VR Half-Life where hand-presence interaction defines every fight.

Execution · Pure Mechanics
Linear military FPS about resisting an occupation of the United States.
Half-Life: Alyx leans Execution (Pure Mechanics); Homefront leans Execution (Pure Mechanics).
Half-Life: Alyx leans a little harder on execution, though the gap is small.
Half-Life: Alyx
VR aim, reload, and grab inputs intense.
Homefront
Standard shooter gunplay carries the campaign
Homefront leans a little harder on reads, though the gap is small.
Half-Life: Alyx
Combine and headcrabs scripted.
Homefront
Multiplayer adds some human prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life: Alyx
Resource and encounter variance light.
Homefront
Scripted setpieces, little randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life: Alyx
Few systems to tune.
Homefront
Modest loadout and map knowledge 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.
