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 · Practiced Mastery
Physical, grapple-heavy combat against learnable boss movesets in an open world.

Execution · Practiced Mastery
Landmark scripted FPS following Gordon Freeman through the Black Mesa disaster.
Crimson Desert leans Execution (Practiced Mastery); Half-Life leans Execution (Practiced Mastery).
Crimson Desert leans a little harder on execution, though the gap is small.
Crimson Desert
Grapple-heavy combat timing and combos demand active hands
Half-Life
Combat aim and infamous platforming sections
Crimson Desert leans a little harder on reads, though the gap is small.
Crimson Desert
Bosses telegraph fixed movesets, no adaptation
Half-Life
Marines flank by script, not by modelling you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crimson Desert
Open-world encounters add mild discovery randomness
Half-Life
Set pieces surprise only on first run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crimson Desert
Learning boss patterns and gear progression drives mastery
Half-Life
Resource routing and encounter knowledge for speedruns
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.
