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.

Execution · Practiced Mastery
A Star Wars shooter that adds lightsabers and Force-power progression.
Half-Life leans Execution (Practiced Mastery); Star Wars Jedi Knight: Dark Forces II leans Execution (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
Star Wars Jedi Knight: Dark Forces II
Saber timing and platforming over huge levels
Star Wars Jedi Knight: Dark Forces II leans a little harder on reads, though the gap is small.
Half-Life
Marines flank by script, not by modelling you
Star Wars Jedi Knight: Dark Forces II
Multiplayer duels existed; campaign AI is scripted
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
Star Wars Jedi Knight: Dark Forces II
Sprawling levels surprise once then map out
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life
Resource routing and encounter knowledge for speedruns
Star Wars Jedi Knight: Dark Forces II
Force power allocation and routing reward planning
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.
