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

Execution · Practiced Mastery
Landmark scripted FPS following Gordon Freeman through the Black Mesa disaster.

Optimization · Practiced Mastery
Resource optimisation and scripted boss mastery carried by strong atmosphere and pacing.
Half-Life leans Execution (Practiced Mastery); Resident Evil Village leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life
Combat aim and infamous platforming sections
Resident Evil Village
Accurate aiming and ammo discipline under varied enemy pressure
Resident Evil Village leans a little harder on reads, though the gap is small.
Half-Life
Marines flank by script, not by modelling you
Resident Evil Village
Enemies and boss phases are scripted, no adaptive modelling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life
Set pieces surprise only on first run
Resident Evil Village
Minor crafting-drop variance; encounters are mostly fixed
Resident Evil Village leans a little harder on optimization, though the gap is small.
Half-Life
Resource routing and encounter knowledge for speedruns
Resident Evil Village
Merchant economy, weapon upgrades and area sequencing are solvable
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.
