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
The original 2003 WWII shooter built around cinematic squad set pieces.

Execution · Practiced Mastery
A customizable Jedi action game centered on deep lightsaber combat.
Call of Duty leans Execution (Practiced Mastery); Star Wars Jedi Knight: Jedi Academy 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.
Call of Duty
Aim and reaction carry the scripted firefights
Star Wars Jedi Knight: Jedi Academy
Saber acrobatics and timing dominate combat
Call of Duty leans a little harder on reads, though the gap is small.
Call of Duty
Light multiplayer prediction; campaign AI is scripted
Star Wars Jedi Knight: Jedi Academy
Long-lived MP dueling scene adds human mindgames
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty
Some spawn and hit unpredictability
Star Wars Jedi Knight: Jedi Academy
Mission order choice, otherwise fixed content
Star Wars Jedi Knight: Jedi Academy leans a little harder on optimization, though the gap is small.
Call of Duty
Memorising set pieces and weapon positions
Star Wars Jedi Knight: Jedi Academy
Saber styles and Force builds reward mastery
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.
