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
A light-gun rail shooter testing reflexes and precise aim against dinosaurs.

Execution · Pure Mechanics
VR Half-Life where hand-presence interaction defines every fight.
Dino Stalker leans Execution (Pure Mechanics); Half-Life: Alyx leans Execution (Pure Mechanics).
Dino Stalker leans a little harder on execution, though the gap is small.
Dino Stalker
Light-gun aim and fast reactions decide survival
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.
Dino Stalker
Dinosaurs charge on fixed scripts, nothing to predict
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.
Dino Stalker
Spawn timing adds modest unpredictability
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.
Dino Stalker
Ammo and weapon management are light secondary concerns
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.
