Building comparison
head to head
Half-LifevsOut of This World
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.
Half-Life
Execution · Practiced Mastery
Landmark scripted FPS following Gordon Freeman through the Black Mesa disaster.
Out of This World
Optimization · Practiced Mastery
Trial-and-error memorisation of fixed death sequences, then executing the learned solution precisely.
Half-Life leans Execution (Practiced Mastery); Out of This World leans Optimization (Practiced Mastery).
Half-LifeOut of This World
Axis by axis
Execution6 vs 6
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
Out of This World
Precise jump and laser timing within tight scripted windows
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life
Marines flank by script, not by modelling you
Out of This World
Every threat is a fixed script, never adapting
Variance2 vs 3
Out of This World leans a little harder on variance, though the gap is small.
Half-Life
Set pieces surprise only on first run
Out of This World
Deaths come from unknown scripted traps until memorised
Optimization6 vs 7
Out of This World leans a little harder on optimization, though the gap is small.
Half-Life
Resource routing and encounter knowledge for speedruns
Out of This World
The game is solved by mapping each screen's exact sequence
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.
